If you're going through hell, keep going.

Things do not happen. Things are made to happen.

I can, therefore I am.

Always desire to learn something useful.

Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

The dog that trots about finds a bone.

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

To know oneself, one should assert oneself.
