BIRTHDAYSSSS!

Guys, next year I turned 15 and I don't know what to do, I mean, I'M OLD, I don't know whether to have a party or something like that, I want advice, I don't know what to study, what did you do at your age? How did you spend your 15 years? It doesn't matter if you are a woman or a man, I want to know, and of course, advice!
