It seems like most people have motivation while they're going to school, but after a forum search, it seemed like these motivations aren't explicitly stated often enough for me to find them. (That, or I stink at using the forum search.)
So, long story short, I'm 31 and have my Associates...
I don't think you have anything to worry about. I'll be 30 when I finish my bachellor's in electrical engineering, and that's only two years away. It's my first degree because I just finished six very busy years in the US Navy in 2004.
