How do you guys make money?

I'm a student but I do a lot of freelance writing and occasionally recruiting and advertising work. However, most of what I do is essays and graduate theses. My main customers are international students at my university, although I do occasionally assist the domestic crowd. This month I have a thesis, four essays, a business plan, and a heap of secondary medical school applications. Based off the rates my customers have already agreed to, I should be making $2,000 in the first half of the month.

Gets kind of annoying, though. I procrastinate a lot so I'll probably end up spending four solid days in the library.
