" In all my studies of happiness, one of the most significant conclusions I have drawn is that there is little correlation between the circumstances of people’s lives and how happy they are. A moment’s reflection should make this obvious to anyone. We know people who have a relatively easy life and who are essentially unhappy, and we know people who have suffered a great deal but maintained a relatively high level of happiness. "
