I know should be blogging. It shows your clients that you can create decent work on a regular basis and helps your SEO. Why don't we blog? For me personally, I dislike writing about my own photos and work. I can write about your work or a product but I can't seem to open up about my own work.
I have been challenging myself to blog. I think you should challenge yourself to post a blog once a week. Then once a day. It doesn't have to be a long winded write up, it could be anything.
