This was an interesting read because I am about to do what you did in your 20s in my 30s.
I actually went through the “corporate slave training grounds” as you mentioned in your other comment and hustled as a corporate slave for a decade. I lived frugally throughout all those years while I saved every raise I got and now I am comfortable doing what I want to do which is pretty much same stuff you did. lol
Wish me luck!
