Know or listen to those who know.

Never complain and never explain.

Problems are not stop signs, they are guidelines.

Expect problems and eat them for breakfast.

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

Quality is not an act, it is a habit.

The dog that trots about finds a bone.

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.
