I wish I did better in high school and college. I wanted to enroll in an MD program to become a neurologist. However, I guess that failure worked out in my favor because... well... I probably would be freaking out right now as a doctor. (Not that there's anything wrong with being a doctor, nurse, etc. during a pandemic. Just saying that I personally would freak out and probably quit. Then I'd have to find a new career or do research because no way in f*** did I sign up for a pandemic, especially as a neurologist who doesn't want to touch sick people in the ER.)

Also, the obvious... I regret not seeking help earlier.
