"The day I stop improving is the day I should stop racing."

I’ve had my best years after fifty. Age is just a number—it’s your attitude that counts. 

The devil is in the details we choose to ignore.

The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease.

领导力意味着今天做出艰难的决策，以便明天让所有人受益。
