This situation can be explained using the analogy from earlier. If one was running on the road to the finish point, where lies a new discovery one has been working for, one may make take the wrong step and take a fall to the ground, which creates a wound in their knee. Even though one gets back up to run, because he got hurt when he fell, one may not be able to run as fast. His new pace will allow him to be able to run slower, allowing him to notice the flowers on the side of the road, he otherwise wouldn't have been able to see because he was so focused on staring ahead.
