How to get better?

I've had a few years of college Computer Science classes.
I've never really tried to get better at programming in my free time.
What are some ways for me to understand programming and computers more? I mean, I know I could just crack a book open, but I haven't had much progress with that.

Thanks for the links.
I was wondering how I could practice to get better.
I've never thought of any real practical use of programming in my life.
