To know how to separate things is to know how to enjoy them. Many finish their fortune sooner than their life: they run through pleasures without enjoying them, and would like to go back when they find they have overleaped the mark... Even in the search for knowledge there should be moderation, lest we learn things better left unknown. We have more days to live through than pleasures. Be slow in enjoyment, quick at work, for men see work ended with pleasure, pleasure ended with regret.
