Never buy anything simply because it is expensive.

There is no doubt that genius lasts longer than beauty.

I gave my genius to my life, but my talent to my art.

I don't mind plain women being puritans. It is the only excuse they have for being plain.

But what is the good of friendship if one cannot say exactly what one means? Anybody can say charming things and try to please and to flatter, but a true friend always says unpleasant things, and does not mind giving pain. Indeed, if he is a really true friend he prefers it, for he knows that then he is doing good.

I don't recognize you - I've changed a lot.

Personally, I have a great admiration for stupidity.
