Can you predict the future with absolute certainty? Your answer must be no. You have two options: You can either decide to accept yourself as an imperfect human being with limited knowledge and realize that you will at times make mistakes, or you can hate yourself for it.

You're not a bad person. But you sometimes do bad things. You know what that makes you? Human.

Don't apologize for what you think you did wrong. Apologize for what they think you did wrong.

If you're self-compassionate, you'll tend to have higher self-esteem than if you're endlessly self-critical. And like high self-esteem - self-compassion is associated with significantly less anxiety and depression, as well as more happiness, optimism, and positive emotions.

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.

Guilt is not the best way to remedy your mistakes.

It can be helpful simply to make a written or mental list of the things you do each day. Then give yourself a mental credit for each of them, however small. This will help you focus on what you have done instead of what you haven't gotten around to do. It may sound simplistic, but it works.
