A lot of the excitement in a project comes from learning: "can I do it," "what will happen," etc.
After a certain point in your life, you grow convinced that you've seen it all before, and that has a way of draining you of excitement. Children are a common tipping point because they also make you less selfish. Nobody is asking you to make those projects, so it has to come from within, and if you act only for others, you never get around to it, because there's always another household crisis looming in the distance.
The only way to pull through is to turn it into a habit, instead of relying on your whims alone.
That's an interesting take on it. I'd never perceived that, but you're right (in my case anyway). I have two children under 6 so there is very little 'pause time' until they are in bed asleep, and by that point I'm shattered.
