It's my belief that history is a wheel. 'Inconstancy is my very essence,' says the wheel. Rise up on my spokes if you like but don't complain when you're cast back down into the depths. Good time pass away, but then so do the bad. Mutability is our tragedy, but it's also our hope. The worst of time, like the best, are always passing away.
So nothing is ever good or bad unless you think it so, and vice versa. All luck is good luck to the man who bears it with equanimity.
Latin: Adeo nihil est miserum, nisi cum putes: contraque beata sors omnis est aequanimitate tolerantis.
