My mother is the main source of this belief, as she always encouraged me to think positively and always scolded me when I spoke negatively. All my life, she insisted on positive thinking and its benefits. My grandmother also encouraged me to think positive thoughts. I've heard it from some admirable teachers over the years. It's completely okay not to question authority figures and role models, which is why I've adopted this belief as one of my own. This belief is not uncommon. Much research has been done on the value of positive thinking. Positive thinking leads to happiness almost by definition. There are a whole host of reasons why I chose to organize this popular forum.
