Short answer is… I dunno. It’s a sickness. I can’t help it.
If I’m being honest with myself though, I think whenever I hit a snag in my writing, where I don’t exactly know what happens next, well, that’s when I’m more likely to procrastinate by designing things. I think of all the things I don’t like about my design, and since I’m always learning new tricks and tips, there’s always something I can improve.
For example, I wanted a site that displayed well on mobile devices, and now I have one 🙂 Whereas, before, I didn’t really know how to do it.
My writing is similar. I’m always getting better and learning new things. You know, when I actually put in the time and stop procrastinating. I guess I should probably get back to it then…
