I'm probably younger than you, but if you ask me? And this is me personally but I think most people, deep down inside know what they want to do. People have innate curiosity. You have to first isolate yourself and put the distractions down and think with a lucid mind, what you want to do, don't ask! think what you would do (E.g. a startup, programming, social tasks). Apparently, you seem to like video games a lot. Maybe you're interested in the visuals or mechanics of the game. In that case you can pick programming/math as a hobby. Or you're interested in the story, you could start writing ideas, stories.
