Well, first you need to ask yourself, "What do I need to go to school for?"
If it's to start your own business, then you really don't need to go to school.
If it's to work for someone else, then you really don't need to go to school.
Let me put it this way, if it's to make money, unless the job requires it you don't need it.
If the job requires it, then the job may be willing to pay for the training. Why not ask the management of the place your working if they have an education plan, and will help with the costs. You might be surprised.
Even McDonald's has a education plan to aid employees.
