When I used to do peyote and applique bead work, I would get upset if I didn't get my rows or my beading just so, perfect. One day while at a rendezvous we were sitting around killing time working on stuff during the day between trailshoots, I messed up an applique on a peice of leather. I was cussing and grumbling under my breath about needing to fix the whole row of beads now. My friend said to me, only God does perfect and you should always leave a little imperfection so your not trying to compete.
I still aim for perfect but don't stress it if it is not up to my definition of perfect.
