The concept that underpins using velocity as a model is displacement in a direction. If we take a step forward, we have velocity. If we run in place, we just have speed. Thus, our progress in a given area is not about how fast we are moving now but is best measured by how far we’ve moved relative to where we started. To get to a goal, we cannot just focus on being fast, but need to be aware of the direction we want to go.
