I was reading Gregory the Theologian's 2nd Oration last night and I came across this passage:
"For hoary hairs combined with pruence are better than inexperienced youth, well-reasoned hesitation than inconsiderate haste, and a brief reign than a long tyranny: just as a small portion honourably won is better than considerable possessions which are dishonourable and uncertain, a little gold than a great weight of lead, a little light than much darkness." (Oration 2, 72)
I've probably read that a half dozen times now, but every time I do it just seems to be more and more relevant (especially the part about well-reasoned hesitation being better than inconsiderate haste).
