Perfection, expect not! Don't seek it

That cucumber is bitter, so toss it out! There are thorns on the path, then keep away! Enough said. Why ponder the existence of nuisance? Such thinking would make you a laughing-stock to the true student of Nature, just as a carpenter or cobbler would laugh if you pointed out the sawdust and chips on the floors of their shops. Yet while those shopkeepers have dustbins for disposal, Nature has no need of them.

-- Marcus Aurelius, Meditations, 8.50
