每一次的努力都是对未来的投资，智者明白这一点。

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.

好的战略通过在最有效的地方利用和应用力量来发挥作用。
