To know oneself, one should assert oneself.

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

Without hard work, nothing grows but weeds.

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

Quality is not an act, it is a habit.

Be gentle to all and stern with yourself.

Never complain and never explain.

Expect problems and eat them for breakfast.

Do not weep do not wax indignant. Understand.
