Your Mindset About Yourself
Your mindset about what you are able to do in life will have a global effect on your entire way of being. Most people view their perceived limitations as real. The reality is that every single person has a tremendous amount of potential.
When you believe that you can do something, you will be able to do more and better than when you believe you can't. Although it's possible to believe that you can when you really can't, you will never know which are real limits and which are imaginary limits until you try to make breakthroughs.
