It's no secret that I am one of many who are addicted to Pinterest. Since I've posted a few original pins, I now realize the pure satisfaction that comes out of other people finding your items pin-worthy. It is validation that what you like or did was awesome/interesting enough for someone to want to save it and share it with their friends.
It feels good even if something you 're-pin' gets 're-pinned', but when it is something that originated with you it's even more gratifying. I modified a chocolate jello shot recipe and posted about it recently and have to admit that I love all the repins! 13 and counting. Go, ego, go!
