join a band and create art.
You will have a ton of time to learn to code and build servers.
I was one of these early bloomers for being a programmer, and you know where it got me?
The same fucking place as all of the other people who started in their mid 20s. Its a waste of time.
Well... I make hundreds of thousands of dollars and have a stable career and I mostly like my job... BUT! My point stands.
There are absolutely diminishing returns for being a "good" programmer, and then it opens up to social stuff. Being able to impress someone with your paintings. Being able to both implement and design a page. Being able to jam with your co-workers after work every once in a while.
If anything focus on school and drill math as hard as you can, it is a HUGE hill to climb later in life.
