If you can envision something as beautiful and wonderful, so it will be. To turn an ugly situation into something good, focus on the positives. Refuse to dwell on what you don’t like or wish you could change. After all, when your perspective changes, the object can too.

to say it simple:

You can’t discover the light by examining the darkness.

Je kunt het licht niet ontdekken door de duisternis te analyseren.
