It is so hard to keep going day after day when working on a creative endeavor. There is always that fine line between work and play. It can be hard to trick yourself into keeping the joy alive- but there are ways to do it. I find Gelli Printing to be a perfect way to infuse some excitement back into the relationship.
Gelli Printing is a form of mono printing, and if you haven't tried it yet, you really need to get your hands on a Gelli Plate. All you need is the plate, a brayer, and some paint. There are lots of videos online, and once you start printing, it is pretty much impossible to stop- until you get too tired and/or hungry to keep creating.
Really though, I think that it is about finding ways to create quickly and intuitively. Gelli Printing helps get me in the right mindset, but it isn't the only way. I hope that you discover Gelli Printing, or something that really gets you excited to create.
