no reason to be unhappy

"Whether we are suffering at present or have suffered in the past, there is no reason to be unhappy. If we can remedy it, then why be unhappy? And if we cannot, there's no use in being unhappy about it—it's just one more thing to be unhappy about, which serves no purpose at all."
