That's the title of a book by Dan Baker. WHAT HAPPY PEOPLE KNOW. And I have to say I usually cringe when I hear this kind of title. But I must say the book has helped me lots over the past few years, which is why I re-read sections when I feel like I'm LOSING MY MIND.
Here's the bit I liked yesterday: "From that day on, I realized that there was something happy people know that unhappy people don't; No matter what happens in life, there's always something left to love, and the love that remains is always stronger than anything that goes against it." (p. 94)
A response like this puts a person in a powerful position, no?
