In the spirit of those kindred souls Voltaire and George S. Patton, here's one way to measure the infinite:
An infinite distance lies between nothing--the unsaid comment, the unwritten letter, the undone act--and something, no matter how much room for improvement remains. In comparison, the distance between that something and perfection is barely noticeable at all.
