Here's a quote from an article, referring to happy people, that I really liked:
"And they all started their journeys as broken people, whether they self-destructed or had unfortunate circumstances or life events come upon them. I know, because I am one of these self-destructing people turned happy. Happy people know suffering more than anyone else, and that’s how they can see just how damn beautiful their lives are. It’s because they’ve seen the depths."
