How to Increase Your Confidence and Courage Using the 5-Second Rule - Introvert Whisperer
Introvert Whisperer / How to Increase Your Confidence and Courage Using the 5-Second Rule - Introvert Whisperer How to Increase Your Confidence and Courage Using the 5-Second Rule Sarah Landrum March 27, 2018 Dealing with Fear No responses Go to top Life is busy. You probably have conflicting priorities, juggle too many tasks and often forget about yourself, which leads to procrastination. However, procrastinators tend to put off the things that are most important, like relationships, career goals and self-care. Ever heard of the 5-Second Rule? No, not the one that refers to your piece of candy that fell on the floor. This 5-Second Rule is one that can transform your entire life. Getting What You Want by Acting on Your Desires Knowing and doing are two different things. You can understand how to perform well at your job, but if you fail to do so, you wont be successful. Knowing how to do something and actually taking the initiative to do it is what will get you results. This applies to what you want out of your life. Do you know what it is you want? If so, have you done what you can to get it? If you havent, youre procrastinating because youre likely stressed. Youll have more opportunities for personal growth and expansion when you step outside of your comfort zone because you will learn more about yourself and what youre capable of. On the other hand, if youre afraid to take risks, you may never know what could have been. Your brain is wired to fight between what you feel you should do and what you know you should do. Its a constant battle, and more often than not, what you think will win. Naturally, people choose to stay in their comfort zones because theyâre afraid of potential stress that can come from stepping out of it. However, this fear will only hinder your personal growth and ability to change the things in your life you dont like. Stop putting these things off. Procrastination is a coping mechanism â" nothing more. You can break free from it. Use the 5-Second Rule to Change Your Life for the Better Say hello to the 5-Second Rule, a tool that can change your life â" if you let it. The 5-Second Rule was shared on a TEDx stage nearly five years ago and is now one of the top 20 TEDx talks in the world. Itâs had more than six million views from over 37 different countries, and its popularity has resulted in tons of positive feedback from people who have applied this rule to their own lives. The 5-Second Rule was created by a woman named Mel Robbins, who was struggling in, life like many of us do. She had problems with her finances, marriage, career and more. She developed the idea of the 5-Second Rule to help her take action and change the things in her life that were making her unhappy. The 5-Second Rule is one of the most popular audio books ever published, and Robbins is now one of the most sought-after motivational speakers in the entire world. Youâre not alone in the world if youâre struggling. In fact, everyone struggles with something. Whether itâs getting out of bed in the morning, completing to-do lists or performing better at work, everyone around you has struggles you dont even know about. While it can be comforting to know youâre not alone, donât let that be enough to continue doing do nothing about your own struggles. But knowing what to do isnt enough, and understanding why you need to do something will also never be enough. You can know something, but that doesnât mean you will do it. It can be hard take the first step and change the things in your life that weigh you down. Easier said than done, right? Not anymore. The 5-Second Rule is the extra push you need to launch yourself into action. Itâs time to get motivated and make changes. Make a list of goals and update it frequently. When you complete a goal, cross it off of your list. So here it is â" the secret to the 5-Second Rule. Whenever you have an impulse to act on one of your goals, you must physically move within 5 seconds, or your brain will just kill the idea. Then, poof â" there goes your opportunity to make a change. Act, before itâs too late. You can break down this technique into three general steps. 1. Acknowledge That Youâre Stressed Focus on what stresses you out. Then, determine if that stress is coming from a real threat or just something you perceive. Its important to have this talk with yourself to understand where your anxiety and procrastination are coming from. Without self-awareness, youâll likely continue down the same path. Take the pressure off yourself and accept that you arenât at fault or unable to change. Here are a few things to remember: Be honest with yourself Trust yourself Donât analyze or dissect Take the pressure off yourself 2. Make a Five-Second Decision to Do Something Once you identify the things in your life that cause you stress and procrastination, immediately do something about it. Donât give your brain the time to react to whether you want to do it. Decide and act. For example, if you know you should lose weight to get healthy, act on the issue right away by tossing out your unhealthy snacks and making a grocery list of better foods to buy. Remember these tips: Go with your gut Confront your stress Act before itâs too late 3. Set Up a Plan of Action The brain tricks you into procrastinating in the first place. When you think about something you donât like or want to do, it can activate your insular cortex, the part of your brain that experiences pain. This way of thinking can naturally trigger feelings of pain, therefore making you not want to do something. Learn to trick your brain when you feel procrastination coming on. Donât think about what you should be doing. Instead, focus on the task at hand, then reward yourself as an incentive. Buy a new pair of shoes, go on a vacation or treat yourself to a nice meal. Remember to: Recognize procrastination Shut out negative thoughts Trick your brain Focus on the task Reward yourself Donât let âI donât want to do itâ become âI canât do it.â Stop yourself in the moment and decide to change your life. Stop your stress in its tracks by acknowledging whatâs causing it, then coming up with a plan to prevent it. Procrastination is a natural, valid response to stress. Cut yourself some slack, but also remember youâre always five seconds away from changing your life â" you just have to find the courage to decide to do it, then act on that choice.

Mid-Year Report Card - Identifying Issues with Study Skills
Mid-Year Report Card - Identifying Issues with Study Skills Evaluating Your Childs Mid-Year Report Card Holiday break is behind us and its a brand new yearwhich also means those mid-year report cards are just around the corner. Many students and parents dread report cards, but they shouldnt, says Eileen Huntington of Huntington Learning Center. A childs report card contains lots of useful information about his or her skill proficiency, academic development, and strengths and weaknesses. Using that knowledge, parents can help their child overcome school problems and be the best student possible. Huntington offers parents a few tips to address different report card scenarios: Issue: My childs report card says he needs to work on study skills. If your child struggles to get focused at homework time (or during class), is overly disorganized or has trouble prioritizing and managing his or her time, talk with him or her about what might help. Try a planner or notebook to record and check off homework assignments and other obligations. Make organization a part of the homework routinesetting up, keeping the desk neat and filing away graded homework. Ask your child what study strategies seem to work for him or her besta quiet room? Taking an after-school break before diving into homework? Issue: My childs grades do not reflect her efforts. If your child spends a lot of time on homework but his or her grades are still suffering, there may be other issues at play. He or she may be missing basic skills or may not understand the concepts covered in class (and struggles to tackle them at home). Visit with your childs teacher to get an approximate idea of how much time should be spent on homework each evening and how you can best support your child. Issue: My childs grades were mostly fine, but he received a failing grade in one subject. It is common for children to do better in certain subjects than others, but a failing grade in any subject is a red flag that your child may not be comprehending class material, completing assignments or putting forth the effort required. Schedule a meeting with the teacher to discuss the reasons behind the low mark and get ideas to help your child bring up the grade by the end of the year. Issue: My childs report card is full of bad grades and she doesnt seem to care. Your child may care more than you think. Many children who struggle in school have low self-esteem and assume their parents are disappointed in them. They stop trying because they would rather get a low grade than experience continued frustration. Resist the urge to punish your child for failing and instead let him or her know that you want to help. Communicate openly about what your child thinks will help him or her improve. Involve your child in the plan of action to encourage him or her to take ownership and responsibility. Theres a lot to be learned from your childs report card, but Huntington reminds parents to keep it in perspective. Report cards and the grades they contain certainly do not measure how smart your child is or the likelihood of his or her success in life, so dont panic if your childs report card indicates that he or she needs help, says Huntington. Investigate these issues with your childs teacher and together, you can help your child raise his or her self-esteem, do better in school and be a happier person overall.

Breaking Good
Breaking Good Well my wife just got back from Bed, Bath, and Beyond, where she needed some thing for the shower or something like that. She told me how the store was full of parents and students from one of the private colleges in town. It was called back to the dorm day for some reason. The reason she brought this up is because she found several of the mothers, and I use that term any way you want to take it, were a bit on the aggressive side. She was pushed and shoved and glared at in line, as apparently these parents saw my wife as one more obstacle to over come. Get out of my way its back to school day in sin city. There is some good news for this educational season. Many students may now be willing to explore Chemistry courses, in their educational travels. The series Breaking Bad showed a desperate and ill high school chemistry teacher turning to manufacturing Crystal Meth as a means to supplement health care costs and provide for his family. It was such a crazy premise that it worked very well. The show was a hit and more students are interested in chemistry than ever before. Well parents welcome to the jungle of preparing your child/children for a new school year. But before you do the kids are going back to school dance, you will have to take them out for their supplies and new school clothes. Shopping with younger children can be an adventure, but taking older, college level kids out shopping can be a real nightmare too. One way around that is to give them a credit card with a strict limit to it and let them have at it. Because some of these stores, especially in the big city, with their back to school sales can be the survival of the fittest. Another important aspect of getting ready for the new school year is to honestly ask the question is your child ready for the next grade level?. If they had a bit of trouble with some of their assignments or subjects last year, you can be sure they will have even more trouble this year. Many students from elementary age on up have trouble with math and sciences. My kids did, as did I, when I found myself going back to school. The weakest area of the typical American student is in these categories. I noticed, in my own experience as an older student returning to school pursuing a Computer Science degree, was the farther along I got in the advanced math courses, the smaller the class size. Not popular subjects in America Im afraid. In fact the sad truth is that we have to bring engineers and scientist in from other countries to makeup for our lack of producing our own home grown ones. So if your child has trouble with math, they are not alone. The main thing that saved me was, a tutor. I needed someone who could translate what the professor was saying into terms I could grasp. When I sat down with a quality tutor before class I had an understanding that I could not have achieved on my own. And at the college level professors do not often have the time for one on one work with students. You can find whatever you are looking for in a tutor at TutorZ.com. And good luck to all in this new school year. Breaking Good Well my wife just got back from Bed, Bath, and Beyond, where she needed some thing for the shower or something like that.

A Literary Narrative On My Physics Journey
A Literary Narrative On My Physics Journey On my trip to Hong Kong, I vividly remember my aunt asking me, as I sat across from her on a bus, âWhat do you want to be when you grow up?â I recall trying to come up with some sort of smart response, but the truth is that I had yet to realize my life goals. After all, I was still an eight year old child. My auntâs simple question stuck with me for the next several years.Soon however, when I was in eighth grade, my academic interests in the fields of science began to call to me.It all began when I picked up the book âA Brief History of Timeâ, written by none other than the great Stephen Hawking. When I first opened the book, I expected to breeze through the chapters as I did with every other book I used to read. However this time was different. The way the text appeared to me seemed different, and it took me almost twice as long to process the words that Stephen Hawking had written down. Slowly, but surely, I flipped through the pages and the magnitude of the universe asto unded me. I barely understood what I was reading, but it felt great memorizing random physics theories with cool names like the Uncertainty Principle or the Law of Thermodynamics. I knew more than other kids at my age knew, and I felt invincible. Soon, I decided that I wanted to be an astronomer, so I could explore the grand space we occupied in order to discover what was really behind the workings of our universe.Inevitably, I eventually bought two more books: âThe Universe in a Nutshellâ and âThe Grand Designâ, both by Stephen Hawking. From morning to night, I was buried deep in the genius that was Hawkingâs mind. My mind was often blown away by the theories that controlled our universe and which made me see the universe in ways that I had never seen it before. The next day, I stepped out the door, and nothing seemed the same. The simplest things, from the leaves rustling to the cold air that blew against my face, could be described by the purpose of a law. Iâd look at one event and think entropy or hold a paper clip and think âWow, thatâs a lot of energy right thereâ. The way I saw my life changed abruptly and my love for physics soared to heights I never thought possible. That was, until I took high school physics.My first year in physics was a nightmare. I went in expecting to learn conceptual theories detailed in âThe Grand Designâ; instead, we learned about boring principles regarding vectors, motion, etc. I was terrible at these principles and I yearned to be in Hawkingâs Universe. The experience scarred me and made me reconsider if I actually wanted to pursue astronomy. However, after struggling through three years of physics, I learned to love it again and decided that I would be a mechanical engineer. To do what, I wasnât sure, but I had an idea. Because I grew up with Asian traditions, I was always taught to prepare for the future. Whether that meant studying hard to get a good job or something as simple as recycling, thos e were the beliefs that I was drilled to believe in.As a result, Iâve constantly envisioned the numerous possibilities of the future. In one of these visions, I stood on top of the Empire State Building. Looking over the edge, I was able to catch a glimpse of New York City...or at least what was left of it. What used to be âthe city that never sleepsâ was now a dead-quiet wasteland. The tall buildings that used to scrape the sky in elegance were broken shells of their former selves. Cars were sprawled across the streets and debris was everywhere. The city was in ruins and what was one the capital of the world was gone as if it had never existed. What really struck me though was the intense heat, which brought me to a sweat within seconds. Everything felt too real and I knew that global warming was too real of a threat to humanityâs existence, but I didnât know what to do.That was until I stumbled upon the book âElon Musk : Tesla, SpaceX, and the Quest for a Fantastic Adv entureâ by Ashlee Vance. With the book in the palm of my hands, I dug in like one would feast at a Thanksgiving dinner. The moment I read the first sentence, I knew that I was in for a ride: âDo you think I am insane?â asked Musk. After the brief introduction, the book began to describe Muskâs difficult childhood and the struggles he had to endure living with his father. This became food for thought because it made me realize that my childhood was rather simple and I had never worked my ass off despite what I thought during state assessments and such. As I flipped through the chapters, my heart began to race and I realized that I couldnât put the book down. His extraordinary inhuman drive to âsave humankindâ by utilizing sustainable energy and space exploration spoke to me and inspired me to pursue the same goal. There was nothing that Elon Musk wouldnât do and nothing he wouldnât sacrifice to complete his vision, and I figured that I must pursue my aspirations wit h the same drive that he displayed.All in all, I still remember when all I did in middle and high school was hang out and shoot hoops as the sun fell through the sky. I regret not doing much more and realizing my dream earlier. But, the book unearthed my life goal and I feel a sense of drive within me that I had never felt before. Now, I want to do as much as I possibly can so I too can âsave mankindâ.
