During workdays, I often have to drive Michelle to her office then proceed to my office. At the end of the day, I pick her up before proceeding home. That means I spend about 4 hours per day driving! In a month that would be around 100 hours or more than an astounding 4 days! That’s a major loss! You only have a fixed amount of time and can’t get any back. If the time I spend driving can be cut down even by half, I’d have 2 full days per month of my time back. Time better spent with Jeanne, for example. Or learning iPhone programming. Or even just sleeping! If that’s not justification for another car, I don’t know what is!
