I visualize the traffic I would have to sit in if I drove a car. The gas I would waste just sitting in lineups, the wear and tear that short repetitive trips put on my car (and our roads here are terrible). The quiet discontent that sets in when I realize I'm sitting in a stationary metal box, separated from the vitality of the world around me.
Then I picture the feeling of freedom that comes from zooming past a line of cars in the bike lane. I think about how invigorating the fresh air feels, and how I'll be saving my car from depreciation and instead making my body healthier by exercising during a time that most people are sitting down. I try to cherish the idea of accepting a challenge to stave off ennui. I try to have fun.
...and sometimes I still drive. Because we're all human, and the air isn't always invigorating. A warm car is inviting during the winter. Sometimes I slept to late. Just commit to doing better the next day, and the next week : )
