David D. Burns said this quote

Perfection' is man's ultimate illusion. It simply doesn't exist in the universe.... If you are a perfectionist, you are guaranteed to be a loser in whatever you do.

Depression can seem worse than terminal cancer, because most cancer patients feel loved and they have hope and self-esteem.

Negative thinking patterns can be immensely deceptive and persuasive, and change is rarely easy. But with patience and persistence, I believe that nearly all individuals suffering from depression can improve and experience a sense of joy and self-esteem once again.

~ David D. Burns

Every time you feel depressed about something, try to identify a corresponding negative thought you had just prior to and during the depression. Because these thoughts have actually created your bad mood, by learning to restructure them, you can change your mood.
