I find that the harder I try to force myself to code, the worse it gets. I like to try some other creative task that can get the juices going and then come back to coding when I have a really great idea. Obviously in a working environment this doesn't always work.

What _else_ do you find really motivating? Could be writing or painting or making youtube videos. It doesn't really matter as long as you're starting to engage creative muscles that you haven't flexed in a while.
