A book that will serve generations with the truth
Format: Hardcover
This is a beautifully designed book. It's narrative includes honest reporting of historical facts. The photos are very helpful toward getting a vivid mental picture of the harsh reality of being a slave in America. It does not a book that promotes negativity, it's just the truth as it appeared. It is very relevant toward promoting peace, understanding and humanitarianism for the ills that plague this country. It's worth the price.

Essential reading for PowerPoint presenters.
Format: Paperback, Format: Paperback
Cliff shows details how to improve our PowerPoint presentations. He gives concrete and simple steps to transform a message into a targeted presentation. All of us have suffered from presenters who went over their allotted time because they had vital information to give us, yet we still didn't know their main point. Many have seen slide decks burdened with dozens of bullet points. Did the volume of points yield more clarity or did they dull our ability to focus on the message? Probably not. Read Cliff's book. Follow his method and you'll be a more effective presenter.
