Keep building and trying new things. School (college and high school) is a great way to be surrounded by other young ambitious people, even if it might not always keep your interest.
Get an internship or mentorship time with someone you admire and learn as much as you can.
Get off the internet and go make awesome shit.
Don't wait to be told what you can and can't do. You can do anything. The world is clay. The most successful people figure that out soonest.
Have fun!
Build stuff you want and you think others like you will want. Basically explore and do things that interest you. There's a lot of value in that.
