Do you ever wonder.....

I love being artistic and get great enjoyment out of creating.  The downside is I always have this little imp sitting on my shoulder making me question if my work is good enough!!  Does anyone else have this problem.  Why the self doubt?  I am trying to create some paintings for an exhibition for later in the year and seem to be getting no where.  I am constantly asking myself if my work is up to scratch, good enough, will people like it.  sigh..... maybe I should just go for a walk!!!
