Here's kind of a different selection for a free pick. Unleashing the Power of Rubber Bands by Nancy Ortberg. This book is currently #1 in The Kindle Store under Business Management, Money & Values and Christian Living.
The book talks a lot about Christian values since Nancy has worked quite a bit with the church. This may put some readers off, so take that into consideration if you want to give this one a try.
This free pick is about leadership. Ms. Ortberg's style is non-linear, so in the book she talks about her mistakes, and gives insights into the world of leadership. The stories she tells pull you in, and leaves you room to put yourself in the story to see how you would react.
This book is inspirational, clear and concise. Recommended for those who want to learn about leadership, and become better leaders in their church, community or profession. It's free, so you can't really go wrong.
