Healthy, positive, and upbeat are not synonymous.<p>My real world academic community is &quot;healthy&quot; in the sense that we get along, have great conversations, and don&#x27;t deride each other needlessly.<p>It&#x27;s also upbeat. We&#x27;re all mostly excited about what we&#x27;re working on and happy to be working together.<p>It&#x27;s not positive. If you say something stupid, we&#x27;ll call it stupid. Some days you will <i>feel</i> stupid.<p>If the goal of a community is to keep everyone always feeling positive, it&#x27;s never going to be healthy in the long run.
