Well CraigL I will tell you how this has affected me, and I used it in my life and business.
First, I agree it is a philosophical overload to which no one person can absorb it all and use it. The author can not even do it. He is an author that can theorize about many things, and yes he is successful, but not because he lives this stuff everyday. You would have to be GOD or some such creature to really REALLY apply all that is in it.
Now, "the look at the end first" part has been helpful for me. It asks that at your death or eulogy what people will know you for? What will they say about you? What will your family think of you? Try planning or seeing the day to day things you do or don`t do as determining what you will be thought of. That tends to have a powerful effect on what you do that day.
Here is and example: suppose you are the best number cruncher for a company that has ever existed. You spend every waking hour doing this. You have a few kids and a wife, and you live, but live to work, because many rely on your number crunching. Than you die. Will you be satisfied that EVERYONE at the funeral could only say WOW he was a great number cruncher. Yep, no one can argue that. George was the best.
I don`t use it everyday, but it is one thing I consider on occasion now. When I find I have been REALLY busy in my life and not having much time to do anything else. I stop and ask myself hey is the contributing to what you want the result of your life to be. Are you going to care about this hustle and bustle in the end? How I answer those questions may change the course of what I am doing.
Now you may say, this is all common sense, and you would be right. However, you asked the question how we can apply this day to day. It is to me a reminder list of how to be a good person and responsible business partner to those around me. Does this help at all? I know you are genuinely asking for examples, so this is mine.
Finally, I could state a case for each step and how I use it, but hopefully this gives you CraigL an answer you were asking for.
