Then, when you find it late, it happens to be the earliest time. Think about whether to continue studying. In fact, you can squeeze out a lot of time when you study in college, which can be used to learn other things.
It will be very painful at first, because the idea of hopeless life is lingering, and there must be a process. Everyone wants to get fat at once, but that's unrealistic. Take your time. Get busy, live a full life, and then get into the habit.
Generally speaking, everyone's situation is different. Don't impose the rhythm of others on yourself (of course, this doesn't mean that you are completely isolated from the world ...). Good luck.
