Change moves in spirals, not circles

Change moves in spirals, not circles. For example, the sun goes up and then it goes down. But every time that happens, what do you get? You get a new day. You get a new one. When you breathe, you inhale and you exhale, but every single time that you do that you’re a little bit different then the one before. We’re always changing. And its important to know that there are some changes you can’t control and that there are others you can.
