Don’t force yourself to figure out what it is you want to become. If you have an idea that’s great. Even if you have no clue don’t force anything. Just explore your options freely. Stick with things that excite you and scare you a little. Try whatever you seem to be curious about and eventually you find that of all the things you try, one will definitely implant itself in your mind and life. You’ll want to keep going back to that idea. This might be the one thing you want to pursue for the rest of yourself. Even if it’s not, do it anyway, and move on to the next thing when you feel like your passion for it fading. Sometimes you’ll go from one thing to another, and another after that. Nothing wrong with that. Just see what excites you the most and brings out the best in you.
