In HS, I would have had more extracurricular activities at least joined some less competitive sports like cross country - there is literally no other time in your life where you will have that kind of free time. I was basically a classic book nerd in HS - very high GPA and class rank but not much else.

In college, I graduated with an Electrical Engineering and Applied Physics degree in 2000. My passion was always software, but at that time almost everyone (in NE Ohio) was giving the advice that electrical engineering would be more lucrative in the long run. I literally read the phrase "the bud is off the blossom" when researching computer science in 1995.

I wound up never doing EE professionally, and have working in software since graduation.

In retrospect, I would have followed own instincts and studied philosophy and math with a minor in Comp Sci. I think the Com Sci minor would be sufficient from a technical side, math would have been a better prep for data science/ML, and philosophy is just good for building mental models and examining your beliefs.
