FLOW QQC

Quote: "Happiness, in fact, is a condition that must be prepared for, cultivated, and defended privately by each person. People who learn to control inner experience will be able to determine the quality of their lives, which is as close as any of us can come to being happy."

Question: Why do they say that happiness is a condition?

Comment: The way that they put how happiness is a condition it's like their saying that happiness is something that must be worked at so hard. To gain true happiness you don't have to work hard for it, it usually just comes it isn't prepared. And what do they mean by inner experiences is as close as to happiness we can come?
