It completely changed the way I work. I'm now a checklist making machine and I find it helps so much, not only with clearly defining what I'm aiming to do, but also with motivation, as each checkbox is a very small bitesize chunk that always seems manageable. I recommend giving it a shot. It's really short aswell so you could smash it out in an afternoon.

If you have the means to "waste" money on the price of the book, I'd recommend it. But by "waste", I mean that the book could have been a thick pamphlet, but publishers sell books and not pamphlets, so by golly that essay is going to get the shit fluffed out of it until it is book-length. So you're paying for a lot of marshmallow cream.

That said, the premise is good and you might glean some good practices that you'll put to use. It's just that it's not worth the $15, IMO. If you have disposable income, buy it. Otherwise, just go read the New Yorker article referenced elsewhere in this thread.

I skimmed it years ago, it could really just be a long essay.

Fun fact, it was a long essay which turned into a book – https://www.newyorker.com/magazine/2007/12/10/the-checklist (https://outline.com/8JS8h6)

I meant to say it could have stayed a long essay. But it was probably more effective as a book, since people hand them out and gift them.
