The CDs cover all topics including selling techniques, leadership, communication, networking, negotiation, and memorizing people's names. You would also get to know the different styles of persuasion. I like the ones from Zig Ziglar & Patricia Fripp. Imagine going to a convention where all these great speakers are present in the stage talking just to YOU. That is the experience you would get from listening to this collection.
These CDs are good ones to listen to while driving your car or when going for a morning walk/jogging.
