In my experience, the best leaders are comfortable in multiple and diverse work and social settings. They are able to adjust their style to meet the needs of their audience or conform to the group dynamics. They understand that a leader without a receptive audience is handcuffed in his/her ability to turn a vision into reality. People tend to connect with others that they feel they can relate to. All conversations are a search for some level of common ground. The quicker you get there the sooner you can focus on the purpose of the discussion.
