I doubt your mind is "used up" Debbie...
One thing I do is look through magazines & books (like the Take Ten, Stamp It! Cards, Cards magazine, & others) with some mini post-it page flags and mark all the cards I like and/or would like to CASE. Then later when I sit down to stamp, I pull out the book/mag and flip to a marked page... feels like instant inspiration.
Sorry if this idea isn't new... it's just something that works for me when I have "stamper's block".
