Regret has a purpose. It's like the oil light on the dashboard of your life, telling you something needs to be fixed. So fix it. And feel better.

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.

People who are prone to guilt tend to work harder and perform better than people who are not guilt-prone, and are perceived to be more capable leaders.

That's one of the peculiar things about bad moods - we often fool ourselves and create misery by telling ourselves things that simply are not true.

Accept yourself. But realize your behaviors can be bad.

When two people respect each other, the ability to be vulnerable and to reveal hurt feelings can create a powerful emotional connection that is the source of real intimacy and friendship.

Confronting your fears and allowing yourself the right to be human can, paradoxically, make you a far happier and more productive person.
