Finishing Pieces

I'm not sure if its because of college where our department emphasized the process rather than the completion of projects or just because I'm afraid of completing things, but I haven't finished a piece in a long long while.  Someone told me that it really frustrated them when they saw me working on something and I ended up losing interest in the piece three quarters of the way through.  For me, finishing pieces is really terrifying.  Coloring, to me, is terrifying.  But I took that someone's advice and finally sat my butt down and "finished" a piece I drew a week or two ago.  (Albeit there are a few choices I have yet to make about it) it's a lot more completed than my other ones.  Goal: COMPLETE!!!!
