Most of us make weekly trips all over town for necessary errands. Find an easy public transportation route, match your trips with a friend, or add extra time to bike or walk. Combine car trips into one route to save money, gas, and time — plus you’ll feel organized. List your weekly trips (you can do this in the notes on the transit page of our book), then rank them from 1 for closest to your home or office to 5 for furthest away. Reorder the list by number in the second column for an efficient trip.
