Do you have any control over it, other than voting in the upcoming elections? Your hope is that your choice will not only win, but be the right one who will make the best decisions for America, whether it's the current president or a challenger. You should vote and your vote counts. So, we've established that you can't really change the world over night.
So, if you must read the news, keep in mind that life is a game. Be interested in it. Be compansionate to others. But always remain non-attached. Let nothing affect you inwardly. However things go, remember, there is nothing permanant or real about it. It’s not what happens in your life that matters, but how you react. Always react with unconditional love and gratitude.
