Innocence

"When we are children we seldom think of the future. This innocence leaves us free to enjoy ourselves as few adults can. The day we fret about the future is the day we leave our childhood behind."
~ Patrick Rothfuss (The Name of the Wind)

"For children are innocent and love justice, while most of us are wicked and naturally prefer mercy."
~ G.K. Chesterton

"And that's what innocence is. It's simple and trusting like a child, not judgmental and committed to one narrow point of view. If you are locked into a pattern of thinking and responding, your creativity gets blocked. You miss the freshness and magic of the moment. Learn to be innocent again, and that freshness never fades."
~ Michael Jackson

Runner-Up. I was confused about the two, but the expressions on this little girl's face won my heart.
