It is better to do one's own duty, however defective it may be, than to follow the duty of another, however well one may perform it. He who does his duty as his own nature reveals it, never sins.
LaoziThat, which others compress - will widen up and open. That, which others weaken - will strengthen. That, which others destroy - will blossom. Whoever wished to take something from the other, will inevitably loose his own.
