While I was having dinner with a well-known author and lecturer, our conversation drifted to money. “I have enough money,” he told me casually. “I don’t need any more money.”

“Of course you can say that,” I thought to myself. “You get fifteen thousand dollars for a lecture.”

Then I caught my thought process, and pondered(仔细考虑)more deeply on his statement. Is he satisfied because he has a lot of money, or does he have a lot of money because he chooses to be satisfied?

I know people with more money than this man, and they still don’t have enough. And I know people with very little money, and they always have enough. So is enoughness something that happens to us when we reach a certain level, or is it an experience we can choose and celebrate at any time?

My friends Adrian and Carey live in a humble cottage in the rainforest. They have quite a modest income, no telephone, and they walk around naked most of the time. I think they are the happiest people I know. They wake up with the sun, love each other very much, and welcome guests with a full and open heart. They appreciate every moment of their lives, have no distraction games going, and are not waiting for the big break around the corner. When I am with them, the predominant（主要的）feeling I have is, “It’s all right here—why would anyone want anything more?”

Ram Dass used to say, “There are three kinds of people in the world: those who say, ‘Too much!’; those who say, ‘Not enough!’; and those who say, “Ah, just right!’”; Since “too much” of one thing implies “not enough” of another, there are really only two approaches to life: lack or contentment.
