This is a must read. I couldn't put it down. Macartney certainly has a realm of experience to draw from and certainly knows how to make this subject matter fascinating. The devil is in the detail and he's found it.
There are a ton of life lessons in here. I had to stop to take notes. There are sign posted action points that are easy to take away. Even if you think you could never act in this way, there are methods that you can use.
I am a particular fan of the Knowledge Protocol. It's such a simple concept when you read it but so vital as well. I am applying that to my life now. The Learn For Tomorrow section is also hugely applicable to how we live our modern lives.
Clearly a 5 star book. Highly recommended.
