enjoy your interests, ignore the mick takers at school, if everybody had the same interests and hobbies the world would be boring, I'm 22, dont do much normal stuff for a 22 year old, drinking and clubbing bores me thats what most other 22 year olds do, i played rugby since i was 6, wasnt a great player, took up refereeing at the age of 18, now refereeing levels of rugby i'd have no chance of playing at, all my friends took the P*** when i quit playing to referee, now whos laughing when i've made something of it, gone far further with refereeing than any of them lot with playing, and still developing! Every hobby if pursued could get you far in life in something you enjoy, for example A bit of amatuer photography of trains at 13, get good with the camera, become a professional photographer when your older,
break the mould, do things you enjoy and are happy with rather than the stuff you see as boring and you'll be a far happier person being yourself.
