Inspiration

I've been struck by a design mind block for the past two weeks. I had a massive spree of creations and then for a whole week, nothing. Absolutely nothing. So here's my question for you. What do you do when you're stuck? Do you take a break from making pieces and just take time off? Or are you one of those who force yourself to come up with X pieces by Y time? I'm aiming to have 100 listings in my shop by Nov which doesn't seem tooo hard but on the other hand, I also gave myself a week off to give my brain some rest. I've found that buying supplies always help kick start the design process but when I spend $US300 on supplies weekly and make a US$25 sale, it really isn't cost efficient. So what other methods are there? (PS, the image is the first that came up in google when you search for inspiration so I went along with it.)
