It's always too early to quit.

Well done is better than well said.

Know or listen to those who know.

Things do not happen. Things are made to happen.

Be gentle to all and stern with yourself.

Never complain and never explain.

Be thine own palace, or the world's thy jail.

The wise does at once what the fool does at last.

Do not weep do not wax indignant. Understand.
