My commute is even shorter than Dujon's: 6m from kitchen to office. Music lessons are reached by tram. Tram or train to the city, or bicycle are the other ways I usually get around.
[INJ] Do you get paid travel expenses? If not, I'd be having a word with my employer, if I were you. Also, are you really out of the house for 15 hours a day (presuming you take 30 minutes for lunch), 5 days a week? Also (Take 2), do you need to be at the client site for all of those hours/days?
My commute these days is a flight of stairs. In my last few jobs it's been: a flight of stairs; a flight of stairs; 27 miles each way by car; 30 miles each way (1 mile by car, the rest by train); 8 miles each way by bicycle; 20 mins walk; 17 mins walk; 25 mins walk etc.
