If we are made aware of things, that is what we think about. I believe that the 24/7/365 news cycles that spew only negativity are a major contributor to the increased negativity/evil/violence in the world. We have wonderful positive actions going on all around us everyday, but they are not "broadcast" or sensationalized by the media. These are more the norm than the exception, therefore, they are not "attention-getting", which is what the media revolves around.
May I suggest that you turn off the TV, radio, etc. and actually LOOK for positive things going on around you. Someone smiling at another, opening a door, offering a hand, comforting another. You get the idea. Focus on good & it will show up. Better yet, BE the good & life will improve....I promise. An insurance company (of all things) has commercials that show people observing others doing kind, helpful things & they, in turn, pay it forward. It creates a domino-effect of good. Very inspiring. Think of that & employ it. It will spread like a good virus. Things can & will get better if WE make it happen. It doesn't have to be a huge campaign, just everyone doing a few small things. Like a snowball, it will grow. Hang in there, & know that there is more love in the world than hate. Focus on the love.
