Thats a really good question and it really depends on what kind of person you are... for example, artistic person will naturaly gravitate towards artistic stuff, someone who loves to "dig" inside cars will naturaly gravitate towards similar stuff. Get to know yourself and answers will unfold, and also dont let yourself to fall into the traps of closing yourself off because "i have already chosen one thing and im gonna stick to it", no if you for example are piano player that doesnt mean you shouldnt lean to draw, play other instrument or even code a video game. Theres also this thing... your desires, do you want to be respected? do you want to be someone famous? do you want to be rich? do you want to have great love? etc. My conclusion is that its really all up to you and your nature, try things, see what feels good for you, see if its correlates with your deepest desires.
Good luck
