For better or worse, I have tons of opinions and information I want to share. I have Google Doc upon Google Doc of random notes, half-written articles, etc. So I'm rarely lacking for content.
And fortunately, I have a lot of variety and autonomy in my work. So when I don't feel like doing one thing (e.g. book writing), I can do another (e.g. working on a psychology experiment). When I have writer's block, I just don't write.
