Well, in my experience, figuring out just the right abstractions to use 
is the difference between a huge pile of code that really doesn't quite 
work right, and a much smaller, simpler, more capable program. 
Unfortunately, figuring out the best way to divide up a given problem 
usually requires a lot of trial and error. (I was just starting to get 
good at it in OOP... now I'm back at the bottom. Heh!)
