The answer was yes. I asked myself. I just knew that I was depressed. We may be motivated to think painful thoughts. At first that may seem ridiculous.
Lets start with the motivation to feel low self concept.
Sometimes people put themselves down because they are angry at themselves for doing something foolish. By punishing themselves in this way they hope they will prevent themselves from doing it again. The temptation to blame others is an example of such a motivation. Supposing we do something that causes a problem and a man give us constructive criticism so that we won't do it again. We can react with acknowledging that the criticism is correct and thanking the person who gave us the constructive criticism.
