Do not weep do not wax indignant. Understand.

If you've got a talent, protect it.

The wise does at once what the fool does at last.

Never complain and never explain.

The dog that trots about finds a bone.

Problems are not stop signs, they are guidelines.

Quality is not an act, it is a habit.

Know or listen to those who know.

To know oneself, one should assert oneself.
