Go through a handful of your past poems and try to identify one or two (or more, if you’re feeling ambitious!) works/techniques that you use most often. Re-write one of your poems without using this technique in order to approach the subject from a different angle. If you’d prefer, you could also write a new poem completely without the technique, but keeping the same subject seen in your older work. The idea is simply to approach an old subject from a new perspective to see what comes of it.
