If to talk to oneself when alone is folly, it must be doubly unwise to listen to oneself in the presence of others.

Don't show off every day, or you'll stop surprising people. There must always be some novelty left over. The person who displays a little more of it each day keeps up expectations, and no one ever discovers the limits of his talent.

For a thing to remain undone nothing more is needed than to think of it done.

Knowledge without wisdom is double folly.

Character and intelligence are the poles you talent spins on, displaying your gifts.

When you counsel someone, you should appear to be reminding him of something he had forgotten, not of the light he was unable to see.

All victories breed, and that over your superior is foolish or fatal.
