"Nothing works out according to plan, but it always works out."

Local motto in Chihuahua, Mexico, from the book Born to Run: A Hidden Tribe, Superathletes, and the Greatest Race the World Has Never Seen

"...[W]e overestimate how happy we will be on our birthdays, we underestimate how happy we will be on Monday mornings and we make these mundane but erroneous predictions again and again, despite their regular dis-confirmation. Our inability to recall how we really felt is one of the reasons why our wealth of experience so often turns out to be a poverty of riches."

Daniel Gilbert, "Stumbling on Happiness"
