Make a budget and stick to it. Only buy necessities. Take public transportation and don't eat in restaurants. Eat ramen noodles morning, noon and night. Recycle cans and bottles. Rob a convenience store. Hold up some guy in an alley. Become a pimp.
In a nutshell you spend as little as you can possiblly get away with spending !
work 60 - 80 hr/wks and do not spend it
there is a site called opinion outpost, check it out they pay you for giving your opinion
