He who stands on tiptoe
doesn't stand firm.
He who rushes ahead
doesn't go far.
He who tries to shine
dims his own light.
He who defines himself
can't know who he really is.
He who has power over others
can't empower himself.
He who clings to his work
will create nothing that endures.

What is a good man but a bad man's teacher? What is a bad man but a good man's job? If you do not remember this, You will get lost, No matter how intelligent you are. It is the great secret.
