During the last 30 years I have worked with many business tools and models to help my clients grow their business. Recently I had a chance to read David’s book and was incredibly impressed with the model he has built and the simplicity it provides in helping clients. David has taken a lifetime of learnings and shares a very powerful but simple to use approach to helping a business grow and prosper. My definition of a great tool or model is one that can actually be understood, implemented and used on a continuous basis. I highly recommend anyone reading this treasure and seeing how they can make their business more successful… Thank you David for sharing your wisdom.
