Yeah, sometimes i'll let the stylus just dance around the page... for no other reason than to loosen up and find inspiration.

you know how you see dragons and bunnies in the clouds? it's kinda like that... you make a whole bunch of chicken scratches and when something starts to speak to you, you flesh it out. really easy to do with digital since you can just drop a layer on top of what you've drawn.

if you ever find yourself running out of creative juices, maybe try that... just zone into it, let the stylus wibble around and see what happens.
