I'd love to see Mountains Beyond Mountains by Tracy Kidder about Paul Farmer on this list.

Books I adore that helped me change the world:
Strengths Finder 2.0 - Tom Rath
Everyone Communicates, Few Connect - John Maxwell
Love Does - Bob Goff
Born to Win - Zig Ziglar
How to Win Friends and Influence People - Dale Carnegie

I love all these books.
I added This Changes Everything: Capitalism vs. The Climate
because naomi Klein shows exactly where it is going today if we don't act now.
And I added the book I wrote The Battles: A Fabulous Odyssey Seeking The Secret of Success and Positive Thinking.
Because, honestly, I wrote this book to help to change the word. This is my contribution to make our world better, one person at a time. We face so many challenges today, but all together, we can change the world and make it a better place, each one using their own skills. Every effort counts.
Hope you appreciate.

The Five People You Meet in Heaven is such a powerful book, about the unseen connections you have in life, with people you sometimes barely know. It's a short book, but I've read it several times, and take something away every time.

I have just added 9 books to this amazing list - thanks Annette for creating it. All either provide ideas for how to develop the strength or focus to create change, or tell stories of people who are doing that. I have written Goodreads reviews for each of them. They are: Random Acts of Kindness; The Career as a Path to the Soul; A Journal for Inspiration; Be a Change Maker: How to Start Something That Matters; The New Better Off: Reinventing the American Dream; Do It Anyway: The New Generation of Activists; Who Do We Choose to Be? Facing Reality, Claiming Leadership, Restoring Sanity; Peak Performance; Real Kids, Real Stories, Real Change: Courageous Actions Around the World. Enjoy! Peter

So ... which book actually changed the world?
