Negativity bias plagues our media; we want good news but we are drawn to bad news, hence "bad news sells".
I would distance yourself from news and TV if you haven't already- There are so many wonderful, positive things happening in the world, by the boat loads.
We are a fascinating species.
Remember, what you put out into the world, is the space you create.
Writing this article about evil and "bad feelings", will cause everyone who reads this to focus on that same thing. Imagine yourself on stage (this post being your stage) and you have a theater filled with 1000 people. Now, imagine you begin talking about "bad feelings" and all of this evil and darkness... all 1000 people will have your attention and you will have directly caused 1000 people to focus on and think about all the dark in the world and more of it will therefore be done.
You have power, your voice has power.
Now, shift to a positive post.. or a funny post. You will then cause all 1000 to think of happy things, positive things or funny things and it more likely that more good will be created.
Peace and love to you.
