Not a whole lot. But when I was 9 I started trying to fix an old Compaq computer that my parents replaced. I never actually got it to work but I did tear it apart and put it back together. Eventually a friend's parent gave me a a Dell that didn't work. Figured out it just needed a new HDD. Around that time my dad (who is literally the textbook definition of technically challenged) got a old textbook about computer hardware from a friend of his that was a bit of a hobbyist. This was in maybe 2006. The book was from 1988. I don't remember the name but it's somewhere in my parents house still. I didn't get much out of the book. Time passed and I started building computers. For myself, the local library, my friends. I ended up going to college for business while building computers on the side. I was making pretty good money for the amount of time I put into it. Eventually I ended up switching careers. My parents didn't really help me get into software but they offered encouragement. And a book from 1988 about computer hardware... So that's something.
