Keep pushing it, as best as you can. Also radically change your stimulation. What inspires you? Expose yourself to different and new ideas. And freewrite, a lot. Use free-writing as a way of getting words out without the pressure of having to produce something of high quality. Switch off all the voices in your head that judge or analyse your output. Do you journal? Take up sketching, just as another creative vent. Play around with photography; grow a pair of fresh, new eyes through which to see the world. And who are you currently reading? How often do you strike out looking for new poets that delight and engage you? What are you reading beyond poetry? Find a poem you like (or don’t like) and rewrite it, or answer it. When was the last time you went to a poetry event that you weren’t reading at? Find an event and go to it, in service of your own writing (as well as supporting poetry). Again, if you hear a poem that strikes you (for better or for worse) try to answer it with a poem of your own.
