The curse of never finishing

I've been putting the creative pursuits on the back burner for a spell while concentrating on more pressing matters (I had a GCSE biology exam recently which was a bit of a stinker!) but now that it's out of the way I've been attempting to finish off the unfinished pics on my computer (and there are a fair few) and complete some of the unfinished models as well.
My creative process generally goes like this:

1. Start a drawing or comic strip or model.
2. Keep going with it until I hit a snag - for example, I'm making a model monkey and can't quite work out how to do the feet, or have done a cartoon but am really struggling with the colouring stage.  There is usually something that keeps the process from being straightforward.
3. Abandon it for a later date and start something else.

Very rarely do I simply sit down and see something through to completion in a single sitting.  As a result an awful lot ends up never getting finished, and this is one of the issues that keeps me from being properly functional as a creative person.  Also, one's failure to finish things contributes, in itself, to a general sapping of morale ("what's the point in starting anything?")

Anyway, a couple of pictures have seen completion this week, which has helped to boost my enthusiasm somewhat.

One is a business card.  I've been meaning to get around to this forever as I'm always meeting people, telling them about my work, and having nothing to give them.  Recently my good friend Mark organised an exhibition in his church to which several people contributed and some of the folks who saw the work expressed an interest in purchasing it.  This included some of my pictures and some by another lady, Barbara, and neither of us had left anything with our contact details on, so getting connected with potential customers was more complicated than it needed to be.

And here's another piece.  A big part of being functional as an illustrator or cartoonist is not only working when you feel like it, but keeping on going after the buzz has stopped.  If you only ever do it for pleasure, it should be left as a hobby rather than a career.

(By the way, the rainbows in the above picture were a complete nightmare to do!)
