Napoleon Hill (1883-1970) – one of the first writers of personal success literature, the author of “Think and Grow Rich” (1937, 20 million copies sold), and an advisor to President Franklin Roosevelt – once said:

“Your mind has a secret invisible talisman. On one side is emblazoned the letters PMA – positive mental attitude and on the other the letters NMA – negative mental attitude. A positive attitude will naturally attract the good and the beautiful. The negative attitude will rob you of all that makes life worth living. Your success, health, happiness, and wealth depend on how you make up your mind.”
