Is it possible to work full-time while going to school part-time?

It's definitely doable, but it's not easy. My mom's graduating with her BA this year, and has been working full time (in a high stress field) and going to school for almost ten years. It's slow going, especially if you can't take more than a class or two at the same time. You'll be stretched thin for a while, no doubt about it. It's also frustrating if you want to have a social life, but that's the price you pay when you're working that hard. You really have to want it. It'll be worth it when you finish.
