As others have stated, this is another practical and clear book from Tim Calkins. Many of us as we approach the later phases of our careers often think that we are good at presentations. I read Tim's book and realized that I had gotten lazy with my presentation preparations. While on a flight to the west coast, to present to a potential new client, I revisited Tim's concepts and used them in my presentation the next day. The presentation and discussion went well - and I'm still working with that customer. Tim's book is very worthwhile.
