I have a day job, but I don't necessarily want to dialogue with it. I may argue with it a good portion of the eight hours I punch in, but I have other avocations that make more appealing partners. One is musical theater writing. I've worked on a children's musical and besides dialoging with my actual composer/collaborator, which is the most satisfying, my journal serves as an ideal stage to work out the answers to what drives the piece in the first place.
Some of the questions I pose consist of "What does the main character want?" and "What is the musical about?" When I ask what it's about, I don't mean the plot. The plot is what happens, scene by scene. Instead, I mean what deeper meaning is the piece trying to bring out? If it's about belonging, does the character discover that he or she can belong or that it may be impossible to really belong. If it's about connection, what might a character do to continually reinforce disconnection before finding a path to connecting with other people.
If working on a play or musical, you might have a journaled dialogue with your character asking directly what he or she wants, believes, avoids or regrets. You may not only find out your answer, but also find ways to smooth any bumpy parts of the script your characters trip on or redirect their steps when they wander away from where they and your piece are ultimately headed.
