The author essentially goes on to abstract away each thing included in a circle. Take a car or a computer or even an essay. It does take knowing what makes the thing up, which is the exercise.
When done completely, unabstraction leaves you with nothing in the circle. Everything can be abstracted away.
In the case of "I" I make another circle around everything I moved outside the original circle and label is "own". It's what I am responsible for and what I will own up to. I own my mood, my health, the well being of my loved ones, my skills, etc. Then everything outside even that? Should not bother you at all.
But on a day to day basis, you can really only do one thing in any given moment. So remapping the "things" that make up "I" is handy, but most of the day most of it is completely irrelevant. That's an important realization also. If I'm writing this here, my "imperfections" should not be on my mind, and will not be.
I also talk to clients about being better than perfect, because perfect doesn't exist anyway. When doing fulfillment, errors do happen. Even amazon ships the wrong item from time to time. So perfection is impossible. But what if you owned up to your mistakes and engaged your customer and gave them more of what they wanted? They feel the attention, the appreciation, and a deeper connection with you and your service. That's better than perfect.
Fault tolerance doesn't have to just make up for a negative. It can go beyond and provide positives that you otherwise would not give.
A purely analytic objective statement about one thing the Bible kind of gets right: God loves you for who you are. Just think of how pragmatic that is. It prevents us from wasting our time murdering our village of weirdos, as per the article. Of course, historically, humans are known to murder the weirdos in our villages, so that's kind of ironic.
