Daily Contingencies
Do you allow for contingencies? Most people prepare for the obvious ones, but not the more routine ones.
Example: if you live in or travel to the northeastern U.S. during the winter, you always need a contingency plan. A case in point was a recent cross-country flight I took back to New York. I was scheduled early enough in the day that had there been delays, I still had better odds that I’d make it back that day.
