I've got some young college friends who seem to have plenty of time to learn how to dance. They take dance lessons and participate in all sorts of dance exchanges.
Personally, I can't imagine doing that as an undergrad. We always had way too much homework to do, and way too many tests to prepare for. It was a safe bet that we couldn't take a weekend off. I was a double major though, and I was in some pretty demanding fields.
I almost wish that I had pursued some more leisurely degrees, but that wouldn't have satisfied me at the time. I think I would have regretted it.
