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 himselfcan'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. If you want to accord with the Tao, just do your job, then let go.
Lao Tzu
