Whenever I get down about life going by too quickly, what helps me is a little mantra that I repeat to myself: at least I'm not a fruit fly.
If the universe were just electrons and selfish genes, meaningless tragedies. . . are exactly what we should expect, along with equally meaningless good fortune. Such a universe would be neither evil nor good in intention. . . The universe we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil and no good, nothing but blind pitiless indifference.
