Any experiences or tips on how to get 15 again in terms of productivity? :)
I guess in your case, you would probably have to get some sort of job where they are a lot more lenient and give you time for side projects.
Keep up the good work kid, try lots of stuff out now, find something you like, then go deep. It only gets more fun :)
On top of that, add chores (if you have any), family events, and other misc distractions I'm sure you don't have that much free time. I mean, don't sell yourself short. It's not like you just get to work on stuff 16 hours a day and nothing else.
Sadly, I'm 36, married with a < 2 year old son. Wife is social (so lots of distractions) and I'm an escapist (love to read) and lazy, so I'm seriously envious of you and the OP's dedication and success at such a young age.
