Yes! I love that book! It's done wonders to my productivity.
I understand and agree that it's best to focus on the highest priority thing first. But how do you identify what the "one thing" is at any given time?
Usually it's pretty clear, e.g. you can say to yourself in the morning "If I complete X today, it will have been a good day". Yet somehow at the end of the day you will have spent all your time doing everything but X.
How’s it different from deepwork?
They could share similar ideas! I put it on my reading list :)
