"Many people spend a great deal of energy arguing for their own limitations; "I can't do that", "I can't help it, I've always been that way," "I'll never have a loving relationship," and thousands of other negative and self-defeating statements".
"Our minds are powerful instruments. When we decide that something is true beyond our reach, it's very difficult to pierce trough this self-created hurdle. When we argue for our position, it's nearly impossible. Suppose, for example, you tell yourself, "I can't write". You'll look for examples to prove your position. You'll remember your poor essays in high school, or recall how awkward you felt the last time you sat down to write a letter. You'll fill your head with limitations that will frighten you from trying. In order to become a writer or anything else, the first step is to silence your greatest critic -- you".
