I have this same exact problem! Always up for some motivation! The interest people's how here on Steemit really helps me keep posting but I get stuck alllllll the time . Especially if I think the idea is good. I try to make it perfect in my head before even trying. The thing I am learning right now is something someone told me in chat ....done is better than perfect....just start....and I should know this because it's what I love about zines! One of the whole vibes of them is just throw some shit on the copier and make it art ...put it out there...it feels great and the raw feeling is actually so natural ... Refined and edited peices are also great but I think there is a place and a reason for doing wild creations with less inner critic ! Ok that's my rant and I am typing in my phone so hope it makes sense haha!
