Today is the day after the American holiday of Thanksgiving. I have experienced this day 69 previous times in my life, and I know that about a year from now this day will come around again. It will keep coming around, even if I won't be around to see 69 more of them.

Time is a flat circle. We have passed this way before, but we are not regressing. This is progress, even though the cycle repeats itself. But now we are aware that time truly is a cycle and we can be as sure of this cycle as we are that seven days bring the start of a new week.
