> It make me incredibly narcissistic and allowed my brain to think in a very "the universe is on my side" kind of way, and I was open to a lot of magical thinking and woo woo after the trip.

That's why it takes a sufficiently mature (in terms of rationality, emotional intelligence and moral values) mind for a trip to be actually safe. One can reach it sooner or later or never but I would consider 25 (when your prefrontal cortex development actually peaks and you have already have gained your fair amount of general experience) a reasonable mean and recommend avoiding psychoactive substances (unless a competent professional decides the opposite and is going to supervise) if you are significantly younger, no matter how legal in your state they are.

BTW the universe actually is on your side. The moment it's not you're dead.

> I made a lot of goofy choices with too much idealism and gusto and not much of a plan and it set my life and career back when it didn't work out.

Why do you believe that's bad? I would say a life without goofiness is a horror. A world without idealism is hell. Some choices setting your life and career back occasionally are inevitable and can actually bring immense value you just don't (immediately or ever) consciously recognize. My life/choices has always been a disaster but prepared me to and at some moment "has put" me in a specific place where I have met my soulmate who turnt my life in a paradise (long proven sustainable and, arguably, even antifragile).

> I am not the center of the universe

Well, you can't prove you aren't and numerous philosophers (and some Everett interpretation enthusiasts) would say you are. And this doesn't mean you have to be a jerk.
