I would... Burninate stuff? Naw, I'd be one of those Chinese dragons that bring good luck. Mainly cause they look cool. So I guess i would fly around n stuff, nailing all the pigeons whit my projectile feces.
I would probably go to mount everest and live at the very top... hidden under a blanket of snow, and when the un suspecting climber stumbles upon me, i will awake and ask him what he wish's for, then i would say i granted his wish, and i would ask him for all money in return... after wards i would eat him...
