I also commute to work, 31 miles round trip, because I love doing it. I did everything I could to enable me to do so. I'm now up to making that trip 3 times a week. Probably wouldn't want to any more than that.
Luckily my commute doesn't really involve much traffic at all. It's mostly rural. And I still love cars and driving, also, so when I do drive it's not all bad.
It's definitely nice to ride somewhere else for a change, though. I did 45 miles on Saturday which is my longest ride ever, to date, and it was a blast. For one thing I rode in areas with LESS HILLS than what I have to deal with on my commute, which was nice. Many more route options, also, as it was much more urban than the mostly rural commute.
