Are you "a star where you are, but little known anywhere else? That limits your future. The more people, peers and more senior people who know you the better your future prospects are. In effect, the more widely known your brand is, the more "buyers" there are. Who do you eat lunch with or hang out with away from work? Are they the same people most of the time? Break the routine and sit with someone else at lunch. Call someone in another department and ask if they would be willing to have coffee and help you understand how your department connects with them. Are there volunteer groups that do Habitat for Humanity or other civic projects. Try one and let other people learn who you are. Some day, maybe sooner than later your name will come up in their conversations with others. The more people who know you as a person, as well as a professional, the more likely your name will be in the promotion pool.
