I love this quote! We should all live by it! Change it a bit and see how pertinent to your life it is:
"I have come to the frightening conclusion I am the decisive element. It is my personal approach that creates the climate. It is my daily mood that makes the weather. I possess tremendous power to make [a child's life/my partner's life/my life] miserable or joyous, can be a tool of torture or an instrument of inspiration. I can humiliate or humor, hurt or heal."
It is so easy to be a thundercloud in your own life. Raining negative energy everywhere you go just because you are a little annoyed or tired or sick or lazy.
I tell the kids, you never know what your coach or teacher or the checker at Acme has going on in their lives. You can't control when and if someone is gonna "rain negative" all over you for no obvious reason. I truly believe that people don't wake up and aspire to be an asshole that day. It just happens sometimes.
We can only control what WE do - how we self-talk, how we react, our actions. The difference can be slight, maybe just a smile to the Acme chick, but that little difference could be ALL the difference.
Rain positive today my friends!
