As an educator, soft skills are your most important tool to have in your arsenal. I like to equate being an educator to being a coach of a team. A coach is a motivator and instructor, and to be successful you'll have to understand how to communicate with different types of people and personalities. Finding ways to keep the enthusiastic students engaged while bringing the less enthused to a level of excitement that keeps the lesson going smooth are signs of a strong educator. A great coach knows that keeping the star player motivated and properly prepared isn't going to be the same as talking to the least experienced player on the team. Soft skills are what keep the group moving towards a common goal the main objective.
