Take a break and try again.
I'm a firm believer in stick-to-it-ive-ness, but I'm also a firm believer in taking a break. And I know when I need one. Yesterday morning I took just such a break from writing and the break was rewarding.
I feel so much more refreshed, far less stressed, and more determined than ever to work on my book projects - I have two currently, and juggle the projects depending on my mood.
I read the same way - usually a fiction novel at the same time I'm reading something non-fiction, and this seems to work for me just fine.
Most of the time.
But when I need a break I NEED A BREAK. And yesterday, I was happy to get one.
How about you?
