I skimmed it too, and I didn’t expect to like it. Not saying that as a personal jab towards you OP, but sometimes members post these long essays that meander, and can be quite dry. As I was skimming, I was hoping you’d give some tactical ideas of how to “live well,” putting it into practice, and you did. It reminds me a bit of Stoicism, and its general principles.
I agree with the others that you could take pieces of your document and offer it up as thread topics here, making it more forum-friendly. It would be better, from a discussion perspective. As with many philosophical ideas, how you would go about working towards peace of mind, and how another person would, obviously will vary based on personal experiences. Many people for example, have experienced trauma in their childhoods, and peace of mind can feel elusive until they heal. But, a blueprint is helpful, which is what your essay feels like to me.
It’s not something that everyone will agree with in its entirety of course, but if people take at least one or two positives away from it, you’ve succeeded.
