Positive mental attitude (PMA) is a concept first introduced in 1937 by Napoleon Hill in the book Think and Grow Rich. The book never actually uses the term, but discusses about the importance of positive thinking as a contributing factor of success. Napoleon, who along with W. Clement Stone, founder of Combined Insurance, later wrote Success Through a Positive Mental Attitude, defines positive mental attitude as comprising the 'plus' characteristics represented by words as faith, integrity, hope, optimism, courage, initiative, generosity, tolerance, tact, kindliness and good common sense.

Positive mental attitude (PMA) is the philosophy of finding greater joy in small joys, to live without hesitation or holding back our most cherished, held in high esteem, and highest personal virtues and values
