How can we be confident and remember something better?

Self-confidence is cultivated slowly, not that you don't want it (overconfidence), but that you don't want it (lack of self-confidence). According to your situation, it obviously belongs to the latter. First of all, I don't know if you have been lacking in self-confidence or have been stimulated by something. If you keep doing this, you might as well do something within your power. You can make some work or study plans for yourself every day and stick to it! Hold on! It's done. These are all things you can do, even you should do. You may not feel anything after a day or two. Stick to it for months, half a year or a year, not to mention that you finish the plan every day, 95%. Stick to it for a year or so and look back at such a long career, study or work. If you can't find confidence, you come to me. If you are stimulated, there are two solutions. First, get up from where you fell. Second, forget about it completely. As for remembering things, because everyone's memory is different, the cycle of remembering things is different. "Cycle"-that is, if you remember something in June 1 and forget it on the 3rd, you need to remember it again on the 3rd. This June 10 and June 10 can be recorded again, and it can be recorded for another month ... This is just an example. After three memories, you can remember for a lifetime, some people can remember for a year, and the people with the worst memory are the elderly (you know the reason). As long as your memory is better than that of the elderly, you can remember one thing for at least a year or two after several memories. Finally, in fact, whether you are confident or memorizing things, you just need to remember an idiom-"Diligence can make up for mistakes" and do it with your heart! Do it hard! Keep doing it! You are sure to succeed. ....
