What helps you with writer's block?

One of my favorite tricks when I have been staring at a passage I'm not happy with for too long is to open a separate word document and then trying to capture the idea without limiting myself to just the small string of words I initially set down.

(Once the words are in front of me I find myself trying to rearrange them as I don't have a much broader vocabulary to choose from.)

Another is to have a scratchpad where I can set aside entire paragraphs or chunks I'm not sure of, but not ready to part with just yet. Some of them become different stories or can be used for later.
