A well-designed system should be easy to use, easy to understand, and easy to modify.

To be an artist you have to give up everything, including the desire to be a good artist.

质量从来不是偶然的；它始终是智慧努力的结果。

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。 

It makes sense to be busy living or busy dying.
