Do you find yourself dwelling on negative thoughts about yourself. Repeatedly putting yourself down, criticizing yourself, comparing yourself to other people you think are perfect? When you make a mistake, do you think it’s absolutely awful, that anyone else would have done a better job, and that it's an example of some permanent flaw you have? If so, then, like many people, you are often your own worst enemy, negating everything you do and blowing things up as if your mistakes are the worst that anyone can imagine.
