There is a story they tell of two dogs.
Both dogs, at separate times, walk into the same room. One comes out wagging his tail while the other comes out growling.
A woman watching this goes into the room to see what could possibly make one dog so happy and the other so mad. To her surprise she finds a room filled with mirrors.
The happy dog found a thousand happy dogs looking back at him while the angry dog saw only angry dogs growling back at him. What you see in the world around you is a reflection of who you are.
