Loyalty

A professional is someone who can do his best work when he doesn't feel like it.

A man reserves his true and deepest love not for
the species of woman in whose company he finds
himself electrified and enkindled, but for that one in
whose company he may feel tenderly drowsy.

Don't flatter yourself that friendship authorizes you to say disagreeable things to your intimates. The nearer you come into relation with a person, the more necessary do tact and courtesy become. Except in cases of necessity, which are rare, leave your friend to learn unpleasant things from his enemies; they are ready enough to tell them.

But love is blind and lovers cannot see The pretty follies that themselves commit; For if they could, Cupid himself would blush To see me thus transformed to a boy.
