I actually started programming around 16. I built my own social network.

I actually used it as reference for my first programming job at 18-19.

Just build something you're passionate about. At the time I wanted to be like Steve Jobs/Bill Gates.

Who are your heroes? Any website / apps you want to make? Any games you want to make?

I suggest you learn a language like Swift or JavaScript and build a webapp, iphone app or iphone game.

Since you are young, maybe you can program something you and your friends want?

Good Luck!
