Welcome! Your English isn't bad at all, and from what I've seen posting on forums in English will help you improve a lot, or so friends of mine on a different forum have told me. Aww your 18? I feel old now! (I'm 28). Well you still have your whole adult life ahead of you when I was your age I wanted to be a vet and it took me until now to really nail down what I really want to do, so don't sweat it! Try a lot of different things and see what calls to you Good luck!
