"Great book"
It's a really good explanation of the behavior of the people around me, why they do or don't do things.
I can use the information provided to make changes in the company I work for, in my family, in my own behavior... I definitely will try.
"Life changing"
This is one of the best books I've ever listened, it's not a complex theory but a very easy and doable set of practices to become more proactive and take control of our own feelings and our responses to the things happening around us. It can also turn us into more easygoing, more friendly and productive people. Highly recomended listen.
