I used to bike 50 minutes twice a day (13 and a half miles each way) through London - and I can honestly say I loved it every day.
Some days I'd wake up feeling tired and grumpy, but once I was on the bike I'd be fine. Some days it would start raining just before I was going to leave for home, but still once I was one the bike everything melted away.
I totally agree everyone is different, and living closer to work would have been nicer. But by living far away I was able to: afford a house not a flat, afford a car for when I wanted to take journeys that actually cost more by train in the UK, live near huge green open spaces - all the while working for the UKs biggest media organisation and getting all the benefits of that and of living in London.
I ate listening to music on a commute, so it was 50 minutes of silence, 50 minutes of either planning my day or shaking off my day. When I'd get home I'd be totally chilled no matter how my day had been, and I'd get to work with a full plan of my day - or if I wasn't busy I'd just let my mind wander onto a million what ifs.

I currently can't cycle and I really miss it - zoning out on the tube isn't the same, working out isn't the same, and it's hard to force yourself to cycled 25 miles a day if you aren't aiming to get anywhere.
But I can totally see how you could get the same from a car journey, or from just being at home earlier.
For me I have to work where I work now (central London), and I love living where I live.
Man I need to get back on my bike!
