If you could go back to when you were 18, what would you do differently?

I'm turning 18 in 2 days, and looking back I realized I've basically been messing around with creative stuff for most of my life. Since I was around 10, I've always enjoyed drawing, messing around in DAWs, making random things, and just experimenting with whatever I found interesting. I never really had a plan behind any of it. Never made anything good but at least I had fun. Somewhere along the way, I also got into competitive programming, so I ended up spending a lot of time learning how to code.

I've never seriously thought of myself as a game dev before. So I'm curious what would you have done differently if you were 18 again?
