Not a young gun, but one thing I did when I first started playing was mow my neighbors yards and shovel snow. If your fourteen or older and live in the midwest, you can make TONS of money detasseling corn. I never did that, but all of my friends did, and they made BANK!
i payed for paintball by reffing at my local field and asking around the house if there was anyone they knew that needed work done, its tiring but its worth it when you get paid $100 to pull weeds for an elderly blind guy (did it last week )

Hard work definitely pays off. Most of my friends that just play video games all day can't even afford a $5 lunch buffet. I have a job, cut yards, and flip car parts and paintball gear. Because of that, I'm driving a Nissan 300ZX to school everyday, have all my own paintball gear, I can afford to go out on the weekends, and I'm even looking to buy another car right now.
Mowing lawns is a good start, get a job if your old enough, and lots of people need help with yard work. Also if you live near any farms see if they need help, its good work and helps you build muscle.
