The Dock

Uncertainty is the day after you fell in a lake. You crashed through a rotten board in the dock.

You had no idea that the supports under the dock were rotting, and you didn't even know that was possible, and you'd walked on that dock every day for years.

The next day, even after that section has been repaired, you start to look at every dock and you see rotting supports under it. And you lose the joy of walking out and sitting with your legs in the water and enjoying the peacefulness.
