“It would have made things a lot easier if we understood there was no way of living that can immunise you against sadness. And that sadness is intrinsically part of the fabric of happiness. You can’t have one without the other. Of course, they come in different degrees and quantities. But there is no life where you can be in a state of sheer happiness forever. And imagining there is just breeds more unhappiness in the life you’re in.”

Matt Haig, The Midnight Library (Page 179)
