Make yourself necessary to someone.

"Every ending is a beginning in disguise."

All men are liable to error; and most men are, in many points, by passion or interest, under temptation to it.

创业就像驾驶无人机，既要有远见，又要随时准备应对突发情况。

释义：杜绝不良嗜好，禁止过度欲望，从而摆脱牵累；抑制错误行为，减少邪恶之事，从而消除过错；减少饮酒，远离美色，从而保持自身清白。这是对修身养性、克制欲望的教导。
