We humans, perhaps believing ourselves to be a cut above most of the other species sharing the planet, sometimes underestimate the odds against us. We imagine that merely because we are willing, able and ready to get where we want to go, that we will get there on time. No need to rush. Well, we've all seen where that kind of thinking leads. The habitually late never budget enough time for the curve balls, the ice on the windshield, the spilled cup of coffee, the dog's surprise pile on the rug, the thousand little snares which slow the pilgrim's progress.
Some people simply accept the consequences of being late everywhere they go.
Others try to outwit time itself. In this latter category, our family evolved a system familiar to many. Rather than set our main clock to the correct time, we set it 10 minutes ahead. The theory being that we would prepare ourselves sooner, thinking it was later. Well, as anyone can tell you who has tried this method, sooner or later, we get wise to ourselves.
