“Happiness is not a zero-sum game. It's the only case in which the resources are limitless, and in which the rich can get richer at no expense to anyone else. That day in the park, I found it remarkably easy to own my happiness and celebrate Kate's as well.
It's a strange thing, though, how rare, maybe impossible, it is to have everyone you care about thriving at the same time. For a short spell, life seems certain and stable, until something shifts and redistributes, randomly, unpredictably, and when you look around at the new landscape, you see that it's someone else's turn now. You redirect your attention to focus on the friend in need. You hope - you know - they will do the same for you, when your turn comes.”
