I have a few relatives in a bit of a bind right now, I would help them out and give them some extra. I would then give my one friend the money he needs to buy this building in town and turn it into Uncle Sam's Misguided Children paintball store and stadium. I would spend 2-3 years in Thailand training at a Thai Boxing camp. I would then spend another 2-3 years travelling the globe learning various martial arts from their birthplaces. I would then enter MMA, and use some money to start up my own gym, with kids getting free admission, where I would also teach Martial Arts, while living at my cabin in the woods, which I would stock with a wide variety of weapons, both archaic and modern, that I would train with regularly. It would be just close enough to a town that I could go into to town if I needed something. Keep just enough for me to live off of, have an emergency relief, and donate the rest to rebuilding Haiti, and developing other struggling countries.
That or start a samurai village and throw the rest off a bridge.
