Dr. Napoleon Hill said, “Whatever the mind of man can conceive and believe it can achieve”. Norman Vincent Peale remarked, “Empty pockets never held anyone back. Only empty heads and empty hearts can do that”. Robert Kiyosaki observed, “The idea that it takes money to make money is the thinking of financially unsophisticated people. It does not mean that they are not intelligent. They have simply not learned the science of making money”. Quoting Brian Tracy, “Your most valuable asset, in terms of cash flow, is your physical and mental capital, your earning ability”.
