Know or listen to those who know.

To know oneself, one should assert oneself.

Do not weep do not wax indignant. Understand.

Be kind whenever possible. It is always possible.

You never know what motivates you.

By failing to prepare, you are preparing to fail.

The dog that trots about finds a bone.

Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.
