‘Actually, I just wrote a book criticising all this happiness business, the positive-psychology bandwagon. I think it’s crap because, sadly, we’re not designed to be happy. Homo sapiens, we’re like birds or animals, and they’re not designed to be happy, right? From an evolutionary perspective, happiness is just a tool, a sort of signal to direct you to seek resources which were essential for your survival. When do we feel happy? When we eat or have sex. That’s just a signal that you are a functioning human being.’
