I enjoy drawing, but often enough I'm too caught up with other things. I whine enough about it, but doing something is nice too:
I now put my daily sketches up on the wall, no matter how good or bad they are, no matter what's on them. If they're bad, so much the better - I can only take them off once I've filled the wall, so I'd better get drawing pronto. Seeing how little I'm happy with them makes me want to do more so I can get the ugly, old ones off the wall.
Perhaps it's silly, but it seems to work for me so far!
