For me, I can't force it either! I 've spent many a lovely time cruising the gallery or pinterst, watching you tube demos, etc. It was fun & relaxing! For a very long time I made one or two cards per month and was perfectly happy with that small amount.
I have never done the challenges, but I know that helps many get going with creativity.
I say just hang out here and slowly ease back in and see where your desires take you.
Are there any stampin groups in your area? I have three different SU demo's classes that I attend.
All I want is the chance to prove money won't make me happy!
