The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.

Learning is not a matter of trial and error, but of insight.

最好的领导者是那些知道如何跟随的人。
