The PMA/NMA Coin
In positive thinking, your mental attitude is often referred to as a coin. It’s an apt description. You have two forms of mental attitude: a positive mental attitude (PMA), and a negative mental attitude (NMA). Just like the heads and tails of a coin. And just like a coin, it can be flipped very easily and it will never come to rest on its edge. This means there is no third option of a neutral mental attitude. It is either positive or it is negative.
