How can I call myself a writer when I spend so little time writing?

One of the fascinating things about my job is how little time I actually spend writing. Like for instance, right now I’m working on a case study for one of my clients (a global office furniture manufacturer). But before I begin writing even one word of the case study itself, I already have more than 8 hours logged into the job: e-mailing and corresponding with people, setting up interviews, sending them questions, doing the interviews (5 in all), transcribing the notes, etc. etc. It’ll probably only take me 2-3 hours to write the damn thing (600-800 words) but all that upfront stuff takes up 80% of the job! Amazing.
