You should arrange a time every day to reflect on yourself. The best time for this reflection is to lie on the bed or sit at your desk after washing up at night. After washing up, your whole body will relax, which is more suitable for deep thinking. You can write everything after reflection in your notebook and make a detailed and orderly review of your day.

Reflect on your own words. Recalling what you did in a day and what you said to whom you said. What words are said to make you think are very appropriate, and what words seem awkward and affect the atmosphere. Especially for words that seem awkward, how should you answer next time and how to avoid it.

Reflect on your own behavior. Which behaviors you benefit yourself and have a positive effect on others; what behaviors you suffer from hurting yourself, what should you do next time, and how to avoid it.

Reflect on your time, energy and arrangements. Your own time and energy are the most limited and the least wasteable. Time and energy are the cheapest, because if it is wasted, it is worthless. But time and energy are also the scarce and expensive. If you make good use of it, you can realize your dreams. If there is wasted time and energy, how to arrange it reasonably is a serious question.
Reflect on yourself every day, make yourself sober every day, and thus make yourself progress every day.
