Know or listen to those who know.

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

Things do not happen. Things are made to happen.

Only the educated are free.

Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

I can, therefore I am.

Do not weep do not wax indignant. Understand.

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