Just wait until you get older, things that involve money get compounded, I made a decision at uni 2001 to not study ai, I decided bitcoin wasn't worth it when that dude bought a pizza with it, bought a house too late and just before the financial crash. I did notice that bad shit was about to go down or at least the potential to at xmas 2019 with covid, not that there was much I could do about it. (Probably due to playing pandemic)
Most decisions in life are a gamble, and usually the odds are stacked massively against you, so don't worry about it too much
