Wherever you're sitting right now, take 5 seconds and look around the room to see how many blue things you can see. Go! 5, 4, 3, 2, 1. And how many green things did you see while you were doing that? That may be a bit confusing for you, but here's the point: what you look for is what you see. So if you want to look for negative things, boy, you will see them. But equally available are the positive things too, the green things. So next time you're focusing on something negative, whether it's the news, whether it's something that's going on in your life, remember blue and green. If you're looking at blue, you'll see those negative things. Change for green because there will be something positive there too.
