Ok, if I really dissect that, I'll find it isn't true at all. I still come up with ideas. 90% of them may involve the same characters, but they are new ideas, at least. I've come up with a bunch of ideas for editing my book. I still somehow manage to write a blog post three times a week (mostly), although that can often be a struggle. I even wrote three paragraphs on Friday night. They were from a scene in Book 3 and I may not even use them, but at least it's something.
But there's still that mental block that tells me I can't do it anymore. I remember in high school sitting at my desk with a notebook using every second of down time to get words onto the page. Why is that so hard now? I used to write poetry all the time, but I haven't in years. The ideas just don't come to me anymore.
I know I have several different reasons for not being able to write. I know what they are, but I still can't bring myself to just push through them and do it. Maybe the answer is to just stop giving a crap about what other people think, or how horrible the words come out. I can always rewrite. And I can certainly just write something for me. Just keep working on it until I like it and then maybe try to send it out into the world and see if someone else does.
As I'm writing this, I'm realizing that maybe that is my big hangup. I never write for me anymore. I try way too hard to get things perfect. I want the words to already be perfect in my mind before I even try to write them, so most of the time I just end up staring at the blank screen. I think I just need to not give a crap anymore. Write what I want and then see how it goes.
