Whenever I go somewhere, I have two goals: 1. To get there the quickest and shortest way possible. 2. To beat the projected time on the GPS.  One of the worst things on a trip is when I see that dreaded "recalculating" pop up, especially if I'm in unfamiliar territory.  Sometimes it's important to change course, though.  Whether it's road construction, bad traffic, or a realization that the life you're living can be better, more impactful, there are certain times where "recalculating" our destination is a great thing.
