Hmm. It's already afternoon, and I barely have an idea for my assignment. All I have is the vaguest of thoughts about a place that I've been to several times. I'll have to write it out and see if it fits together and leads to some sort of life lesson.
Sometimes I don't like doing that because I don't always want to go where my writing takes me. Depends on my mood. I just want to get a block of time and work on it.
