Your Success and the quality of life you will enjoy is tied tightly to the degree in which you believe in yourself and the commitment you exercise in growing that belief to the point where it meets the truth of who you are and are meant to be. Here is a fantastic perspective:
Your skepticism, which you presume is based on rational thinking and an objective assessment of factual data about yourself, is rooted in mental junk. Your doubts are not the product of accurate thinking, but habitual thinking. Years ago you accepted flawed conclusions as correct, began to live your life as if those warped ideas about your potential are true, and ceased the bold experiment in living that brought you many breakthrough behaviors as a child. Now its time for you to find that faith you had in yourself before.-Price Pritchett
