Many times we think that life is a flat road without imperfections, but we have never stopped to see the ground for a moment. If we observe it with a magnifying glass we would see that it is quite unstable. We tend to think that we can run at extreme speeds, but it is not true, we will always stumble upon something no matter how small. The question we ask ourselves is: Why? The answer is very simple: we do not watch only run.
