If a fisherman does not have a properly repaired net, then his trip is useless.
Preparation is the major part of his endeavor. Only when the fisherman keeps his
nets intact, keeps his boat repaired, and studies the conditions of fish and
water does going out to fish become a mere formality. Then fish fall into his
hands as if guided by invisible lines.
