The One Thing

I had a long to-do list and not much to show for it. That was the problem.

Keller's argument is that success is sequential, not simultaneous. You don't achieve five things by spreading yourself equally across all of them. You achieve one thing at a time — by asking what matters most right now and doing only that.

The focusing question at the heart of the book: what's the one thing I can do such that by doing it, everything else becomes easier or unnecessary? I started asking that every morning.

Not a perfect book. But the central idea is one of the genuinely useful ones.
