1. Preference principle. Only if you like this thing, you can stick to it when you meet a strong opponent, and you will not give up when you encounter extremely difficult situations, and you will not waver when you are greatly shaken.

2. Be good at speaking principles. Only by doing what you are good at can you do it well. Only by doing what you are good at can you be better than others and have core competitiveness.

3. Value principle. You must think that this matter is important enough before you can do it, otherwise you will not be happy if you do it well. The job you choose should be valuable, not just for some reason.

4. Development principle. First of all, you should send it by mail. If you have the opportunity to do it, you must have a strong market and a strong room for growth. Only in this way can we have a career.
