GO TO COLLEGE!! I'm 24 and just finishing up my freshman year. But it is so much fun. I love learning. Most schools offer some online courses so that you don't have to show for every class. And most online classes have discussions that work just like this and other forums so it's a breeze.
For those of you that are in your 30's and didn't go, you can still go. Start in a community college at night and transfer out. My co-worker who has been working here for 10 years decided to go back. (she dropped out when she got married). She's having her 40th birthday and in her senior year of college. She's not planning on leaving this job, but you never know what will happen tomorrow, so it's good to have a degree to cushion any fall.
