Ways to cultivate one's morality:

1. Don't always worry about tomorrow, and don't always regret what happened yesterday. Concentrate on what you want to do today.

There is nothing we can do about what happened in the distance. Worrying doesn't help anything. So remember, you live here and now, not far away.

3. Accept the unpleasant feeling. People usually want to have happy feelings, but they are unwilling to accept melancholy, sadness and unpleasant feelings. Happiness and unhappiness are relative, and they also exist and transform each other. Therefore, the correct attitude is: not only to accept happy emotions, but also to be psychologically prepared to accept unpleasant emotions.
