“The second principle is to limit your work in progress. Perhaps the most appealing way to resist the truth about your finite time is to initiate a large number of projects at once; that way, you get to feel as though you’re keeping plenty of irons in the fire and making progress on all fronts. Instead, what usually ends up happening is that you make progress on no fronts—because each time a project starts to feel difficult, or frightening, or boring, you can bounce off to a different one instead. You get to preserve your sense of being in control of things, but at the cost of never finishing anything important.”
