Number two is you can only care about one or two things so make them the big things. His point here is people care about way too much stuff in their lives. For instance, let's say your sister is really bad with money and you're always thinking about it. 'Oh no. Why is she getting into so much debt? How can I help her out?' Mark Manson is saying that's outside of the realm of your control so you shouldn't worry about it. The example he gives in the book is one of his friend's sister was getting married and then the brother, his friend, didn't like the guy that she was getting married to so he was like constantly like talking up to the sister about how that was a bad idea, talking to the guy about how he shouldn't be getting married. And his point, Mark's point in this book was that it doesn't really matter. Worst-case scenario or not even worse case scenario. Let's say the sister gets married to the guy the only thing that this guy gets from worrying about the marriage is now he's super stressed all the time because he said all this bad stuff to the boyfriend, now husband, and his sister doesn't like him. His sister is mad because he's been shit talking the marriage the whole time. The better approach according to mark and I'm seeing the light in this as well is just to be hands-off. Realize that you can only care about one or two things so the friend and really all of us should just care about making ourselves succeed and in best way we possibly can and not worry about whether all your friends are having kids and you're not or whether you're getting older or you're losing your hair or any of the stuff that we worry about.
