This document discusses why people love museums and what makes them sustainable. It argues that people love museums because they provide experiences that make visitors feel the same way museum professionals feel about their work. Museums need to let visitors share in these experiences to build love and support. When people love and value museums, they are more likely to support and engage with them, making the museums sustainable. The key to sustainability and building love is for museums to focus on sharing experiences with visitors rather than just objects and facts.
