Change is inevitable. Growth is optional.

程序测试可以用来显示错误的存在，但绝不能显示它们的不存在！

When public speaking， pause frequently. Pause before you say something in a new way， pause after you have said something you believe is important， and pause as a relief to let listeners absorb details.

领导力就是让他人因为你的存在而变得更好，并确保这种影响在你离开后依然持续。
