Know or listen to those who know.

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

Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

The most effective way to do it, is to do it.

Who seeks shall find.

Never complain and never explain.

Things do not happen. Things are made to happen.

Do not weep do not wax indignant. Understand.
