My parents don't pay for anything.  They say this season, I even have to pay my own hospital bills.  They just yell at me a lot and tell me I'm going to paralyze myself and ruin their lives.
I'm not sponsored, but I do get free shit at comps and such once in a while.
I work full time at a state park in the summer.  On top of that, I'm a correspondent for the newspaper, and sometimes I work for my aunt painting and stuff.
Last winter I worked part time as a lifeguard at my college (5:30 a.m. to 8:30 a.m. so I could be skiing by 9) and also did stuff like  housesitting, ski instructing, and putting tags on clothes.
I'm going to try to get a job at a shop this year so I can get free lift tickets and such.
