First, i'd like to commend you for being such a matured person at a very young age. Nowadays, its very critical to startup when you dont have knowledge and passion about what you would like to do. It came from you, you are only 16. Meaning, its never to late to know what you want, what would be the best and what gives you the satisfaction your life has. Dont rush yourself, yes its good to start early, but its better to start the game prepared and ready. I hope i was able to help you. Goodluck on your endeavors.
