"Writing positively helps improve the human."
The word has power, if I made recipes with succulent dishes, their presentation, appearance, ingredients and their preparation, it will not be strange that readers begin to praise and immediately provoke them to taste it, in the same way if I narrated a sad story, I can go as far as making those who read me cry, some authors have that ability to make an impact with what they write.
But in general we can say; that positive thinking, speaking and writing contributes to improving communication, it is not about avoiding or avoiding the things that must be recognized as wrong, but the meaning of what we speak or write to us is aimed at contributing so that we are better every day.
