Projects do not usually die at the beginning. The beginning is easy: the idea is fresh, the possibilities are open, and enthusiasm does most of the work for you. They do not usually die at the end either, because by then the finish is visible and the pull of completion carries you through. They die in the middle, in that long grey stretch where the novelty has fully worn off, the end is nowhere in sight, and the work has settled into something that is simply difficult and unglamorous.
What makes the middle dangerous is that it is precisely where motivation is least available, and motivation is exactly what we have been taught to rely on. We treat a loss of enthusiasm as a signal about the project. Maybe this was not such a good idea. Maybe the interesting thing is that other thing I just thought of. Often it is a signal about nothing more than where we are in the curve. Every substantial piece of work has this stretch. Mistaking a predictable feature of the terrain for new information about the destination is how a great many worthwhile things get abandoned.
The practical conclusion is that the middle does not need motivation; it needs structure, because structure is what works when motivation does not. A fixed slot in the week that does not depend on how you feel about it. A visible measure of progress, so that movement is detectable even when it is slow. Someone who will ask you about it. These feel unnecessary at the start, which is exactly why people do not build them then, and they are the whole game by month four. So, as a reflection for today: what are you in the middle of right now? And what is going to carry you through it, given that enthusiasm will not?
