13 yars old, 90 hours a week = 7 days at 13 hours or 5 days at 18 hours.. C'mon man.. But like raptizzle said, if you want it.. Work at it and make it happen but like everyone else said... Don't ask people who work their ass off for their money, some risk/give their life for their income and your on here asking complete strangers from all over the world to hand it over. I'm sure you can understand why this would offend some people or they see it as a joke. You hadn't even tried to word it in a soft approach, it translates to "will you give me money so I can go play?".
Take a look at how many military, law enforcement, fire, ems are on here that work12+ hour shifts day and night, member that spend months or more from families! And See things that 98% of the population can't even think of. How many farmers there are who actually work 90 hours a week, business owners who have sacrificed the first years of income and struggled to make a new business survive in order to support their families and people who have done well in school and worked hard to do exactly what your asking, to fund their hobby...
Maybe it's your age and lack of life experience but all of these things are taken in to consideration when one of us buys a truck or a new upgrade or goes to an event and then there's a young guy who's first post is essentially begging or pan handling for money on the Internet.
I'm 17, I drive a raptor (which is great if your fortunate enough!) but now that I have the truck I need money to play.. In honesty you may be better to trade the raptor for a mustang and do the race in a few years or embrace the raptor for what it is and try getting to an event.. I bet you'll discover a whole new form of fun, most people can drive fast on a highway.. We do it every day on the way to WORK, give the dirt a try I promise you will like it.
This is the reality, I'm sure many will agree, some are being harsh but I'd bet it's because of the approach you took. Had you started your posts with a different tone I'm confident you would've gotten many congratulations from everyone here like the rest of us did on our first post and especially a congrats for being fortunate enough to have one at such an age.
Good luck on your goals for the future, if you really did work 13-18 hours per day at 13-17 then you have a magnificent work ethic and surely you can do something with that desire.
