There is a lesson in sand. It teaches us the ongoing flow and form of time. We are like the grains of sand being shifted by forces we do not quite understand. By accepting this shifting nature of time and reality, we can enjoy the ebb and flow.
Why wait to wake up? Every second gives us an opportunity to start again, to start moving our lives in a new direction. Even if it feels like an impossible task, even the minutest change can have a ripple effect. Just think where you would be right now if you had started moving in the direction you want to go a month ago, a year ago, ten years ago?
