Don’t limit your carpool options to people you work with. At times that can be great but there are many instances that the 8 hours you spend in the office together is just about the limit of everyone’s endurance. Be open to the idea of carpooling with friends who work in different offices.

If you commit to once a week, you are decreasing your contribution to traffic congestion and carbon emissions by a whopping 10%, and the time spent together isn’t too much to be a burden. We all have a mate whom we wish we could see more often. Get creative about your scheduling and kill a flock of birds with one stone.
