Came here to say this. For me it was just obsessive curiosity and loving building stuff with computers, whether it was websites, or trying to code up a virus.

“Obsessive curiosity” is a fantastic phrase I failed to mention in my response - 100% agree!

Computing is such a wonder to me that I couldn't imagine my life without it. This invention fundamentally changed what it is to be human imo and if you can accept and embrace this fact then everything else comes naturally.
