Perception is all

The time is what you think it is, not what it actually is. I looked at the clock on the wall beyond my monitor yesterday and asked myself if I had time to do something. “It’s not five o’clock yet,” I realized. So I worked away and worked away, and when I looked at the clock again, it was still only a couple of minutes before five. But my watch said five to six and the second hand of the clock was jerking at about twenty to the hour. Dead battery syndrome. And suddenly, it was later than I thought.
