Self Blocking

Why is it that I always have such an active mind?  I'm always wanting to do or learn something different than what I'm doing.  Like right now I'm working on counted cross stitching of a complicated pair of wolves.  I know that it's going to take me a long time to finish and after picking it up again after Christmas this year I was able to finish one square (there are four large squares and four half sized blocks on one side of each square) .. I know it will take me as much as a year to finish so it's an on-going project but my wandering mind is wanting to do something else.  I was into beading, that has kind of went by the wayside, I did a bunch of knitting and that is by the wayside as well, and then I started using Blender to make a digital teddy bear and all of these were, I think, to take me away from my painting.. I think that the reason that I'm not sticking with one craft or art is that if I get really good I think that I will start getting commissions from people and that will make my art a job and will squash my creativity.  Ahhh the self blocking of the troubled mind.
