Role reversal. Do someone else's job for part of the day and create something at their workplace or based on the experience. I partly failed at this, but only due to work circumstances... I wanted to do some ink mixes for our small press, but wouldn't you know – only our large 4-colour press was in operation today, and its four colours come ready to apply. Boo. On the bright side, this was created in the workplace so all is not lost. It's a little recipe card for mixing Pantone 289 (since it's today's day!) should you happen to have some base inks lying around.
