Writer's block is a tough one. Sometimes the words just don't flow. On those days, I do one of a number of things: depending on how many writing projects I have going on at once, I might take a look at a different story. Or I might do some research. Research always gets me back in the writing mood. If those things don't work, I stop writing altogether and do something else. I go out and experience life. I socialize, interact with others, and then...before I know it...the words start to flow again.
