Quotations calcify into clichés.

Quotations cause all kinds of trouble.

If you flatter yourself properly you will be better able to enjoy yourself. Stretch your joy so that others enjoy you too.

Excellent flatterers welcome attentive audiences; mighty potentates enjoy public praise. In the most pleasing situation, a flatterer would genuinely admire the flatteree, please that person, please other present company, be pleased to stagger rivals, and get something out of it: applause, promotion, a favor, reciprocal praise. Flattery is as social as a banquet.

Care for yourself enough to listen carefully to what you say to yourself.

Shakespeare, Milton, and Dryden, scissored, patched, and frayed.

[D]ifferent people have different quotational gravity.
