Even those with raw talent have to practice regularly. Engaging others in professional roles should not be limited to work relationships. You should practice engaging others when possible.
My dad was a teacher, and is still very engaging to this day – partially because of his personality. But it was also a necessity for his career. Could you imagine being in front of a class of kids and not holding their attention? Teachers who could captivate the “crowd” were always the ones that remained memorable to me.
