Cassi Jo - I definitely know what you're feeling, and hope that you find something to build your motivation back up for your shop (because your shop is great!!)
This is always a challenging question to find the answer to, for sure. Things I have tried when I get into inspiration/motivation ruts (these have worked some days while not others, just depends on the rut/wall I'm facing!)
- hang out with my cats - they're really hilarious and petting their furry heads can definitely relax me (and them as well)
- step out of my studio and don't touch anything Etsy related for a day/two days/an hour/a minute - this also includes stepping away from FB, Pinterest, etc. during those times
- go outside, even just to get the mail. Fresh air is good :)
- eat lunch, sometimes I get to the end of my rope and I realize it's because I am hungry, lunch re-sets my system and I can think more clearly about what to do next
- housework! it's distracting and will let your brain process thoughts in the background while sorting, folding, etc.
- sometimes I try not to over-think about something. I distract myself, let my thoughts run in the background in my brain, and then at some point I get an "ah ha" moment. Kind of works the same as if I forget a word that's on the tip of my tongue: I force myself to stop reeling over it, and eventually the word resurfaces!
- draw/doodle/write/sketch also is helpful, I've had ideas come out from just writing a word or starting to draw a line.
This is long, sorry! Best wishes to you in finding your painting inspiration again (would you like to borrow one of my cats? =^-^=)
