每日原则：严厉的爱既是最难给的，也是最重要的爱（因为它很不受欢迎）

恭维的话容易说，但它们不会帮人提升。要指出人的错误和缺点（他们因此学会长进）更难，而且更不受欢迎，但长期而言更为宝贵。尽管新员工之后会感激你所做的，但他们一开始通常很难理解。要取得成效，你必须清楚、反复地解释其背后的逻辑和关爱。

The greatest gift you can give someone is the power to be successful. Giving people the opportunity to struggle rather than giving them the things they are struggling for will make them stronger. 

Compliments are easy to give but they don’t help people stretch. Pointing out someone’s mistakes and weaknesses (so they learn what they need to deal with) is harder and less appreciated, but much more valuable in the long run. Though new employees will come to appreciate what you are doing, it is typically difficult for them to understand it at first; to be effective, you must clearly and repeatedly explain the logic and the caring behind it.
