I recently started a blog after years of thinking about starting one. I've only written a couple of posts so far, but it's been very satisfying. No one else may ever read them, but writing down the words from my head has helped complete my internal thoughts. I usually walk around with 3-4 internal "blog posts" in my head that are just milling around inside my head. Putting these down into an actual blog has filled some void that I didn't even know I had.
