The need to be liked, also known as the disease to please, is not the same as being likeable. The need to be liked by others relates to the need for approval and affirmation. In a leadership position, this can portend disaster and failure when a leader believes being liked by followers is the gateway to getting supported or accomplishing the team's objectives. It is better to be respected than liked. I have coached many leaders about this distinction.
On the other hand, being likeable is positive because it is not rooted in pleasing a particular person or group of people. Being likeable is a strategic skill learned by leaders and sales professionals to become successful in any vocation. Likeability is rooted in the attraction toward an individual. It is emotional and instinctual because we are social creatures. Have you ever liked someone almost instantly?
