What am I thinking?

So I just signed up to go back to school starting in January! Two classes a term for 2 terms and I can upgrade my diploma to a degree..I'm excited as I am a nerd about loving school. However at the same time I'm a bit nervous--one more thing to throw into our time management list. The good thing is that it's only 6 months, but to be honest I feel I'm soooo ready to be done school forever ever.
