That isn't in tune with reality. Maybe a lot of people are lucky enough to experience a life where nothing goes wrong - I doubt it - but there are a lot of disasters in the world where a life can just fall apart.

Someone having a chaotic, even shambolic, life doesn't disqualify them from giving life advice. That is just normal. The best and worst of us have objectively horrible existences filled with disasters. Most people don't talk about the sheer number of things that go wrong because it makes for distressing chit-chat.

Peterson does good work in being open about some of that stuff. That is part of why he is popular.
