Know or listen to those who know.

By failing to prepare, you are preparing to fail.

The dog that trots about finds a bone.

Be gentle to all and stern with yourself.

Expect problems and eat them for breakfast.

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

Never complain and never explain.

Do not weep do not wax indignant. Understand.

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