Sometimes things happen in your life that throw you off balance and you lose focus. Just like a camera when things are too busy or too shinny. I had that visual effect while recovering from my hand injury. But sometimes out of focus can help you see the balance in things. For example, if you want to make sure you have placed your Christmas tree lights evenly, just squint your eyes...or remove your glasses of you are near sighted.
And sometimes looking at the beautiful round balls of light that blend into each other just make you feel happy just like champagne bubbles.
