Train people well enough so they can leave, treat them well enough so they don't want to.
性能的关键在于优雅,而不是大量的特殊情况。
Life is too short to wake up with regrets. So love the people who treat you right, forget about the ones who don’t, and believe that everything happens for a reason. If you get a chance, take it. If it changes your life, let it. Nobody said life would be easy, they just promised it would be worth it.
