"A well-fed man keeps and calmly gives forth his infinitesimal portion of eternity. It sounds big in the summer night. And it is, as it always was down the ages, when there was a man with something to tell, and ones, quiet and wise, to listen." - Ray Bradbury
So the lesson there is... look for any sort of excuse, however silly or arbitrary, to make anything at all. Because everything we do tends to leave some traces of everything that we are.
