It is very hard to be a continually creative person. It is, in many ways, like being expected to churn out 10,000 scarves and only having enough wool for 51 and not ever even getting lunch on breaks. The longer you sit and try to make such things, the worse you and they become. I have become a drained and disappointing individual who has missed a handful of crucial deadlines and, more than that, lost the thread of creativity linking me to the creative ether.
I sort of think it is like the speed force. That mythical construct is built in order to give history and vulnerability to the Flash superhero character. His power comes from the speed force like my powers come from the creative force. Losing access to that source of power prevents me from doing anything even remotely interesting. Now the Flash can get his mojo back through some crazy superhero quest or whatever. I gotta just stick my head in 17 books and try to remember what it feels like to wonder and to create.
I think the Flash has it easy.
