What position in soccer should i play at?

I'm 16 and i'm only 5'7. I've got some stamina and speed on me. i like to play as a striker and am working on improving my weak foot. i can dribble quite well. i like to keep ball in possession and don't pass it which makes my friends and coach furious. I just wanted to ask that am i playing at the right position or not...and if not please tell which position should i play at?
