I'm 32 and just beginning Grad school. I also have two kids but they live with their mother during the Spring and Fall. I won't be taking any summer classes since they will be with me during that time. I am a little older than most who start grad school but I wouldn't have been ready for this until now.
I swear I was 18 until I was 30.
If I had gone to grad school after my first undergrad attempt I would have ended up with a useless couple of music degrees or something like a MA in Chaucer or Beowulf. Not that it's a bad thing, it's just impractical if you want to work I suppose.
Anyhow, I start in the Fall and I think I'll be able to finish it up in three years with no problems even while working full time. Pretty cool, I guess we'll see.
