I can, therefore I am.

The dog that trots about finds a bone.

Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.

Only the educated are free.

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

Do not weep do not wax indignant. Understand.

Leap, and the net will appear.

To know oneself, one should assert oneself.
