向內求而不是向外求

心理學家和哲學家威廉．詹姆斯說︰「每個人都想得到快樂，都在尋找得到快樂的方法，有一個方法可以讓人快樂起來，那就是明白快樂是發自內心的，不是外界給予的。」

Psychologist and philosopher William James said, "Everybody in the world is seeking happiness --- and there is one sure way to find it. That is by controlling your thoughts. Happiness doesn't depend on outward conditions. It depends on inner conditions."
