Moving Complexity

I always feel a sense of satisfaction when I move a piece of complexity from outside an object to inside an object. It doesn't need to be a large amount of code, I've learned. Every little step helps in the long run.

If I could go back 20 years and give myself some programming tips, one of those tips would certainly be this: You don't move code into an abstraction to reuse the code, you move code into an abstraction to use the code.
