My suggestion for blog ennui: take a month off, and maybe in your spare time go visit a few new local places.
Last August I just tanked – I was busy, I was tired, and I was worn out with the heat. Taking a month’s “vacation,” refocusing on other projects, going a few places, and not thinking about posting at the blog was really helpful for me.
I came back fresh for the beginning of autumn, and had a whole bunch of new ideas and pictures to share with renewed enthusiasm. Posting a note to let readers know I’d be out worked well.
Best of luck,
