I'd firstly buy me a better computer station, then buy me 2 more computer monitors. Then, afterwards, I'd go flash the money at the idiot girls who made me feel like crap in the past, and laugh as they try to butter me up. Only thing is, I'd then tell them to hit the bricks , and that it's my money.
My mum..dunno if i'd want anyone else knowing tbh. I would actually probably not tell anyone for awhile, make them wonder where i'm getting all the money from for stuff 😛
I'd tell my friends and family. I'd put about 80% away in a savings account. The other money I would spend on a bigger house, even more electronics, a flight simulator cockpit, etc.
