The secret to planning the invasion of Normandy was that, like all projects that initially seem overwhelmingly difficult, it was broken up deftly into small tasks—thousands of them. This principle applies at all scales: If you have something big you want to get done, break it up into chunks—meaningful, implementable, doable chunks. It makes time management much easier; you only need to manage time to get a single chunk done. And there’s neurochemical satisfaction at the completion of each stage.
