You would think colors are facts, but we can really trick ourselves. See HERE this incredible video.
We see the world, not as it is, but as we are──or, as we are conditioned to see it (Stephen Covey).
So with everything which is not a color, it is the same or even more so! Incredible is it not? What is the color of your glasses? What is your perception and would you like to change it? See how I made a small change just by changing the word BUT into AND.
