One of the big takeaways is that most of this information isn't just professional, you can (and, IMO, should use it personally).
How you handle feedback and responsibility with your direct-reports is going (most of the time) how you do/ought to do things with your own children. And with those you worship with. Valuing personal relationships isn't just for the home and friends: it's important in a business context. Taking ownership/responsibility is something you must do personally and also across all aspects of your life.
The beautiful thing is that so many of us get so stressed out because we have so much to do. However, being a good servant leader—addressing what people need rather than what they want—will often mean that you pass on things to others. This makes them feel more valuable and also means less stress for you. I did this yesterday with my son and the trash. He's got an Apple Watch and an alarm clock. So I told him: you're responsible for the trash. I'm not going to remind you about it, but if you don't do it, you sure as heck will hear about it. He relishes the idea of me not reminding him, and even though it's just taking out the trash—he likes the idea of "owning" it. (Not to mind the fact that he'll be driving in a few years... God help me!)
