I can, therefore I am.

The dog that trots about finds a bone.

Leap, and the net will appear.

Do not weep do not wax indignant. Understand.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

The secret of getting ahead is getting started.

Be gentle to all and stern with yourself.

If you're going through hell, keep going.
