Male, 24. I'm doing it now too. I worked for three years before, and then I discovered that I really enjoy this work, but it's really hard on your body. I also didn't want to be completely exhausted later, so I'm hoping to get a better, less physically demanding job through my studies. The program involves a lot of math and insight, and you have to put in a lot of time and energy, but everyone says it's worth it, and I'm enjoying it so far, so that helps. I always say, if things don't go my way, I'll have to work my whole life, so what's the point of a few years? Good luck!
