There are more productive ways to earn money than a fast food place.

You can search different builders/contractors and call them and ask them if they need any helpers. Often there are builders, plumbers, painters, lawn care businesses, nurseries that may need workers. The thing about working in these places is while you may start on a low level, you can actually "learn" things about each of these businesses. The most important thing to remember is "listen" and be dependable.

I have met individuals that get up at the crack of dawn and they go to a local horse farm and muck stalls for 2 or 3 hours often making $10 and hour under the table, they finish that and go and clean a couple of homes if one is good at that one can make $15 an hour and up, they finish that and wait tables at night and if one can be a good waiter/waitress at a busy place one can make a couple hundred on a busy night. The key is to do a good job, listen, be dependable and people will keep you on.

People who gain wealth always have more than one iron in the fire. So, an example of learning how to do that you would figure out how to work more than one job, create time to start that computer thing you talk about using the money you get from these jobs and continue along that path until the computer thing either takes off, or if it doesn't you are still making money, in a forward motion while you think about another approach where your original goal in this gaming thing might work. That is more of a positive way to "buck" the system in what you are thinking has to mean doing something "shady" in order to make quick money. These shady individuals typically end up at the short end of the stick in "jail".
