Don’t worry about this notion. The stream of creativity is not some tap that can be turned on or off. It will flow naturally and like nature will likely be in fits and starts with periods of almost uncontrollable and frenzied surge and periods of nothing with plenty in between. This is no problem for anyone or any community producing true expression or art as it just doesn’t matter when the stream flows. However, it is a problem for any commercially driven producer of works. That though is of no concern to us who want to concentrate on art rather than commercially inspired garbage.
There are no deadlines; there is no such thing as writer’s block.
