I have four books from Mr. Wallace & Mr. Hamiltion. The knowledge shared in these books are as valid as a Harvard MBA, The Holy Bible, and a semenary would offer. It cares about people, and it shows in its offerings that can take the average mind, even a college educated mind like myself, and put business apps and practices pass the sky. I recommend this library, and wealth of knowledge to anyone I felt had potential to excel in life and in business. The information is so good I would prefer to keep it in the family.
