I wish I had actually bought a bunch of Apple stuck in the 90s when I considered it but the money ended up being spent on other things At the time I was considering it the stock was about $4 a share after splits etc. if I had Id be sitting on about a million dollars today.
I wish I had gone after a degree in Engineering instead of Business.
I've always thought I should have stuck through college and gotten a degree but if I had most likely I wouldn't have met my wife and had these 3 wonderful kids.
Simple. I wish I had discovered organized nudism earlier in life (I came to it around 30) and then completely embraced it. By that I mean lived at (or very close to) a nudist resort. I also let someone else's distaste for the lifestyle affect my ability to practice it full time - huge mistake. I thought they would eventually warm up to the idea, but I was wrong.
