That's really the essence of what there is to it, in my opinion and experience at least. But: I only could start doing that when I was in my thirties. Before that my brain just wasn't up for it. Whereas when I now think about many of the things I did back then, especially the clinging to objects/bookmarks, I can fully see how useless and even ridiculous they were. Life is really better when you can just stop caring. Though it is also pretty hard to do. I know still sometimes feel pain about things I intentionally got rid of even though I know if I'd have them I would not actually use them. Goes to show the kind of tricks a brain can play.
