In my experience, sometimes the best source of inspiration is forced motivation. For a long time, I've really wanted to make progress on my hack but for some reason, I couldn't bring myself to be active or creative. So I forced myself off my laziness and messed around with it. Didn't come up with any ideas, didn't make anything serious, just messed around. That eventually evolved into inspiration as I got back into the habit. I realized that the longer I was away, the harder it was to feel motivated. Sometimes all it takes is a little push. :)
