I find the easiest way is to 'store that idea'. I tend to keep thinking about a project or part of a project so that I won't lose or forget what that thought was about. ("If I think about it a lot, then I won't forget it.") At times like that, I will store that thought, either on paper or as a file with a detailed descriptive name. My mind will then happily let the thought go, as it can now be picked up again at some unspecified time in the future. And then I can now do what I am supposed to be doing, instead of thinking about something else.
