I live about 50 miles from the office. I leave at around 5:30 in the morning and am in the office by 6:30, and I try to get out absolutely no later than 4:00pm, usually by 3:30. So it takes an hour in the morning, and roughly 90 minutes going home. I honestly don't mind the drive at all, but I HATE traffic. That is why I get up so early and leave early, to avoid as much traffic as possible. For me it is either podcasts or audio books. I can find myself totally enthralled in them and not falling asleep.
Luckily I do have the benefit of working from home whenever I need, but since I have 3 small children at home all day it can be very distracting. So really I prefer to drive into the office whenever it makes sense. Really for me the biggest benefit of working from home is saving on gas. If I go into the office every day, it runs me roughly $400-$500 a month in gas. I would like to move closer to work, but there is no way I can afford even a comparable sized house down in the Silicon Valley compared to what we have here.
