Renaissance person

I read this article about a guy who devotes an hour each day to learning something new. He does most of his learning online with free tutorials. He's learned about juggling, Haitian voodoo, and astrophysics. He spent some time practicing to become ambidextrous.

I think often about how I spend my time and how, when I have some free time, I tend to spend it either doing things on my to-do list or lounging around. I love this idea, but it would take discipline to put into practice.
