For me, a big problem was what we call the "Someday/Maybe list." I had a lot of resistance to writing things on that list, because it was framed as "Someday...Maybe..." That sounded so vague, and ...uncommitted. There are things I might not want to act on right away, but I didn't want to relegate them to "Someday/Maybe," because it aroused my skepticism that I would ever get around to doing the thing.
It matters, how we frame things. I now use the word "Sleeper Projects," and I have no problem putting things on that list.
People shouldn't hesitate to customize the wording of their categories, since the exact same word will have different connotations to different people. Personally, I takes the words someday and maybe literally enough for them not to be a problem, but some people prefer "Incubate," or "Deferred." The wording that you respond to and use is the right wording.
