Wanting to write and not being able to is a source of frequent frustration.

I have two methods to combat - ask for one word prompts and characters to do STRICT drabbles for. (this... doesn't work for writers who do long form only)

Or pick up a quick hobby/game/craft that I can do over a couple of days in the time I would usually write. That usually makes the muses come back from the fishing hole begging to get on with words.
