I love the downtime and use it for personal stuff. I am of course chained to my desk and phone. But there's always hobbies and interests to pursue. I seldom get bored.
If I were more ambitious, I could become on of those over-employed people with multiple full-time jobs at the same time. But that lifestyle would stress me out. I also work in a field/area with a gossip network. So it would be risky. Anyone gets caught doing that, word would get around quickly.
