Ramblings of a middle-aged college student

I've come to the conclusion that there are no conclusions. No ends, no completeness (a word)? No finishing. I thought I was done with college studies, and had no intentions of ever needing, or wanting, to go back. Yet here I am studying stuff and learning stuff I didn't think I'd ever give a hoot about. Business Law, computer ...StUfF...,Math and you guessed it! Blogs! It's still early in the game though, and I haven't learned all the new rules.... do you suppose there are a lot of new rules? Cliff notes maybe? Any advice from anyone?
