Contracts are a testing ground for human nature. Sometimes, after multiple operations resulting in consecutive losses, it is easy to get carried away and take a Heavy Position or hold a losing position against the trend. These are all mistakes that can be made due to human nature.

Trading is often counterintuitive, and full-time traders need to overcome even more pain, misunderstanding, and loneliness. Never self-deny, slowly find your own trading rhythm. When things are going well, don't get carried away; when things are going poorly, don't belittle yourself.
