我专注于未来，而非过去。

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.

The greatest illusion of all is the illusion of separation.

"Love and war are two sides of the same coin."

I’m a great believer in solving hard problems by using a checklist. You need to get all the likely and unlikely answers before you; otherwise it’s easy to miss something important.
