Art shows

I have never looked for an art show to enter before, so the assignment of finding five to enter has opened up a huge new world for me.   The trouble i've been having is deciding what to enter, I seem to go through this process of self doubt, as to if what I have is even close to being worthy of entering a competition in the first place.   This is why I like the idea of doing this project and having the possibility of receiving rejection letters.  It is all obviously part of being an artist, and I can't think anything else more humbling.  Tough experiences can be great experiences as long as we have the right attitude about it...
