If you really can't find a goal, then start from your own interests, set a thing that you can persist in doing every day, and then finish it every day. For example, if you like writing, you should write every day. If you like painting, draw a picture every day; Wait a minute. Don't set too big a goal, such as what I want to write and what I want to draw. You just need to do it every day and try your best to do it well. In this way, day after day, after a long time, you will see your progress. You can make a punch book and stick to punching cards every day. How many times you punch in, you can reward yourself with a small gift.
