The Two-List Day
One thing that must happen. Everything else is optional.
A to-do list with fourteen items is not a plan. It is a record of everything you might do, and it guarantees the day ends with most of it undone.
A long list gives every item equal weight, so you naturally do the easy ones. Naming exactly one thing that has to happen removes the choice at the moment you are weakest, and it means the day can be judged. Either the one thing happened or it did not.
Name one thing the night before
Not three. One. If the day contained only this, would it count as a good day.
Put everything else on a second list
The maybes. They are allowed to happen. They are not allowed to go first.
Do the one thing before the maybes
This is the whole discipline. Email and small tasks feel productive and will eat the day if you let them.
Judge the day on one question
Did the one thing happen. Nothing else on either list changes the answer.
