Know or listen to those who know.

Be gentle to all and stern with yourself.

The dog that trots about finds a bone.

To know oneself, one should assert oneself.

Without hard work, nothing grows but weeds.

Do not weep do not wax indignant. Understand.

Things do not happen. Things are made to happen.

By failing to prepare, you are preparing to fail.

If you're going through hell, keep going.
