Cliches aside, you need to give more information if you expect answers. Do you literally know nothing? Do you have interests, anything you enjoy, anything you can tell us so we can give you advice? If you really have nothing, I recommend trying to do everything that sounds interesting, because you'll eventually find something you love. You just have to be active about it. If you have any information to give so that I can give a more personalized answer, say so and we can work with that.
