If you are a coach that works with leaders, I recommend Dr Richard Davis’ book on The Intangibles of Leadership.
You’ll find a review at Braincram.
It has a description of the 10 intangibles that Dr Richard considers as those that have the largest impact on why some leaders thrive and offers a number of ways for developing each characteristic.
I’ll be using some of these techniques in my own practise and suggest you consider them too.
