Any fact facing us, however difficult, even seemingly hopeless, is not so important as our attitude toward that fact. How you think about a fact may defeat you before you ever do anything about it. You may permit a fact to overwhelm you mentally before you deal with it actually. On the other hand, a confident and optimistic thought pattern can overcome or modify the fact altogether.

Norman Vincent PealeWe've all heard that we have to learn from our mistakes, but I think it's more important to learn from successes. If you learn only from your mistakes, you are inclined to learn only errors.
