At the latest, you'd better make your own life plan in your junior year. After two years of college life, you should know something about your study and your major, so you should have clear life goals and plans at this time.

As for the health plan, we should form good habits from the beginning of freshman year and pay attention to the biochemical details in daily life: don't form bad habits or even bad hobbies, don't give yourself a chance to relax, remember to plan ahead, do a good job of exercise for a week, stick to it and live a regular life. I want to do this. I am healthy and more fulfilled. At least in college, it is very helpful to form these habits in life.
