Resonate is a book all about presenting well. I had a decade of powerpoint which is probably enough. Sometimes people use it well, but more often than not they don't. My pal is one of those who knew he needed some inspiration over and above PPT and he found it reading this book. If you communicate in any way this might be the book you have been waiting to read. The author helps Steve Jobs with his presentations which isn't a bad CV.
In the book, Ben Zander is cited as a masterful communicator. Watch this and you will see why. If you communicate with an audience, preach to a congregation or a teach a child then buy this book.
