We affect, and are affected by the people we meet, in one way or another. As a leader, maintaining a positive perspective and consistent way of being is essential; only the inner core of a team should be allowed to see you sweat. Negativity is sensed instinctively and on a subconscious level, through words, thoughts and feelings, and through body language. If you would prefer to be around positive people and avoid negative ones, would you assume your colleagues feel the same way? People are more disposed to help us, if we are positive, and they dislike and avoid anyone broadcasting negativity.
