The second thing is to forget what’s not urgent…
The second thing is to forget what’s not urgent or important contrary to popular belief. Your brain doesn’t multitask. If you’re not fully present, it will be difficult for you to learn when your focus is split.

In the book
Learn the difference, too, between useful and useless thinking: most of our mental noise is narrative chatter, while the truly useful thoughts — the ones that solve a problem or stay with the task — are usually quiet. Forget what is neither urgent nor important, and be fully present with the one thing in front of you, because a split mind learns and decides poorly. Do not believe the lie of multitasking; people who try to do everything at once are measurably less effective than those who do one thing fully. — Decisions & Choices (Decision/Choice/Focus/Forethought/Consequences)
