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.

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.

The biggest mistake you can make in trying to talk convincingly is to put your highest priority on expressing your ideas and feelings. What most people really want is to be listened to, respected, and understood. The moment people see that they are being understood, they become more motivated to understand your point of view.

After all, this is how you learned how to walk. You didn't just jump up from your crib one day and waltz gracefully across the room. You stumbled and fell on your face and got up and tried again. At what age are you suddenly expected to know everything and never make any more mistakes? If you can love and respect yourself in failure, worlds of adventure and new experiences will open up before you, and your fears will vanish.

When we're rational about rule-breaking we set a limit. You don't get 30 years in prison for a traffic ticket. But sometimes you sentence yourself to months or years of emotional pain over minor offenses.

Despite their differences, pride, shame, and guilt all activate similar neural circuits, including the dorsomedial prefrontal cortex, amygdala, insula, and the nucleus accumbens. Interestingly, pride is the most powerful of these emotions at triggering activity in these regions - except in the nucleus accumbens, where guilt and shame win out. This explains why it can be so appealing to heap guilt and shame on ourselves - they're activating the brain's reward center.
