GTD Times: What goes on a Someday Maybe list?

David, a college student, asked: I know David Allen says that it's acceptable to place "pending" projects onto a Someday Maybe list. I have several outcomes that are "one-shot deals." However, I can't move on then right now. Can I place them on my Someday Maybe list?

Coach Kelly Forrister: My Someday Maybe is mixed with possible actions and possible projects.  Anything from writing to an old friend to hiking Machu Pichu.  So feel free to put anything on Someday Maybe as a place to capture it.  Just be sure to review it in your Weekly Reviews (or regularly) to trust you're seeing what's in there.
