What to write when you don't want to write?

 I've taken another hiatus on the Sci-Fi Multiverse book.  There's a lot of redundencies with the Horror Crossover Encyclopedia, more than I anticipated.  There's a lot of sci-fi/horror crossovers.  I don't want to repeat myself but I also want to be all-inclusive.  This has left me frustrated and ready to abandon the project altogether.  My previous venture, Cartoon Multiverse, was abandoned because of my quest to be all-inclusive faced me against Family Guy, where the crossovers never end and I was really sick of watching every Family Guy episode in such minute detail.  

So...  I figured I can spend more time on the TVCU blog.  I love the TVCU blog.  Except, I'm running out of ideas.  I think I've covered mostly everything, except for maybe some topics I don't have enough familiarity with to cover.  I know there's a lot of anime crossovers, which I would have gotten to in Cartoon Multiverse, but I'm really not that familiar with anime.  

I might start doing some more historical figure/celebrity appearances in the TVCU posts.  I love doing them.  Not sure who to cover though.  I've been enjoying doing the essay style posts but not sure what else I want to talk about write now.  

I need a muse.  Some inspiration.  If anyone has any ideas, let me know.  Meanwhile, all I could come up with today to write about was not knowing what I wanted to write about.  

Thank you for your attention to this matter.
