I chose my next job because it was accessible via the Ballona Creek bike path and buses (though the 2 buses made a 20 min drive take an 1hr+).
My current job is a shorter bus trip and a shorter bike ride. I'm not willing to drive 1-2 hrs one-way to work. I want time to be a part of my community, to have hobbies, to do more than drive, eat, sleep, work and to get that time I need a short commute.
If a long commute limits my existence to drive, eat, half hour couch potato, and sleep than the job is not worth it.
