If you do not wish a man to do a thing, you had better get him to talk about it; for the more men talk, the more likely they are to do nothing else.

Talking about a plan gives you much of what doing it would, at none of the cost. The description gets refined, people respond well, and something in you registers the matter as handled, so the actual work loses its urgency. This is why the most discussed projects are so often the ones that never start.

Stop describing the thing and go and do a piece of it. Set a rule that you will not talk about it again until one part exists, however small and rough. If you want to use the same effect on someone else, notice that inviting them to explain their plan at length is rarely neutral.
