Apologies do make a difference. Believe it or not, research shows people often prefer them over money.

More often than not, the belief that you are bad contributes to the "bad" behavior. Change and learning occur most readily when you (a) recognize that an error has occurred and (b) develop a strategy for correcting the problem. An attitude of self-love and relaxation facilitates this, whereas guilt often interferes.

Learn to accept your limits and you'll become a happier person.

The best way to confront your fears it to stop avoiding the situation you're most afraid of.

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.

Forgiving yourself, not guilt, increases personal accountability.

Reaching for the stars, perfectionists may end up clutching air. They suffer from mood disorders, troubled relationships, and stress. They may even achieve less than others.
