I have had the pleasure of knowing Mark Hamilton for only a few months and I believe him to be a very intelligent, sincere gentleman, with impeccable integrity. I have read several of his books and I consider them to be very interesting, informative, and helpful in stimulating my mind gain. I am 70 years old and have been totally retired since June 2003, and Mark’s Neothink books are beginning to reinvigorate me and are causing a desire within me to begin to live again and start creating value for all mankind. And to experience the joy and exhilaration in doing something worthwhile again. I highly recommend Mark Hamilton and all of his books.
