Oof. Yeah, I've done a lot of different styles of commutes (walk, bike, public transit, drive) over the years. My favorite is something that is ~20 minutes door to door involving physical activity (walking or biking). It does help tremendously if you can be flexible about when you arrive/leave as well. Weather is also a concern—I did do a 25 minute walking commute in Boston but it could be a problem with snow and rain.
