Write It Down.

In the knowledge worker environment, competency is evaluated by outputs, interactions, and stories.  We are judged by how we behave and how we handle difficult situations or people.  Those are interactions, and the resulting stories build a reputation. But most importantly, we are judged by what we write.

Consider an expert in a field, and inevitably that person will have a body of work, in a form of a book or a blog or, in the corporate environment, a long email chain somewhere along the way. 

In the knowledge work environment, the best way to be seen, is to write.
