This was valuable advice given by a colleague of mine - "As one goes up further, the biggest battle is to carry along multiple constituencies - well-wishers, not so well-wishers, peers, sub-ordinates, bosses. " For you to carry along someone, you first need to know what the other person is thinking - and that is'nt going to happen unless you there is open, informal communication. Unless you have a feel for the undercurrents, you are not going to be able to sail your yacht through. Understanding undercurrents often does not involve a deep dive, but a consistent ability to take mini-dips, socialize ideas, get other people's perspectives and work on change.
At a personal level, I would like to believe it enriches one's perspective - ability to read and handle other people, understand their fears/insecurities/turn-ons/turn-offs. For me, the biggest though has been learning to think on my feet - you learn to handle the most unexpected questions and perspectives.
Here is a link to an excellent article that does raise some very pertinent questions on this topic.
