To know oneself, one should assert oneself.

Never complain and never explain.

I can, therefore I am.

If you're going through hell, keep going.

Things do not happen. Things are made to happen.

Do not weep do not wax indignant. Understand.

What you do today can improve all your tomorrows.

The dog that trots about finds a bone.

Be gentle to all and stern with yourself.
