Patti Smith said this quote

I believe in movement. I believe in that lighthearted balloon, the world. I believe in midnight and the hour of noon. But what else do I believe in? Sometimes everything. Sometimes nothing. It fluctuates like light flitting over a pond. I believe in life, which one day each of us shall lose. When we are young we thing we won't, that we are different. As a child I thought that I would never grow up, that I could will it so. And then I realized, quite recently, that I had crossed some line, unconsciously cloaked in the truth of my chronology. How did we get so damn old?
