My work to/from work is 25 minutes. I have a habit of walking rather fast but noticed I often get worked up about some issue that's neither urgent nor very important. Only when I force myself to walk at more leisurely pace I find it refreshing.
The funny thing is that driving is maybe 10 minutes faster each way, but I'm way more productive when I ride by bike. I doubt I could convince anyone to let me work 20 minutes less a day when I ride though.
