Why this book?

Capture culture filled our tools and emptied our completions. This book subtracts. The unit of progress is a thing that exists at the end of the day.

What you’ll get

  • 30 insights with daily finish tasks.
  • Special Edition by Daniel Kim, including The Top 10.
  • A paper shutdown checklist and a 31-day finish log.

The 30 Insights

  1. 01

    Calendar first

    Feelings are a poor scheduler.

  2. 08

    Define finish

    If you cannot see the end, you have started a lifestyle.

  3. 15

    Cut until today

    Tomorrow’s slice is how infinite projects survive.

  4. 22

    Protect the shutdown

    An endless day is not dedication. It is a missing ritual.

  5. 30

    Publish a small finish

    Public is how work escapes the private museum of almost.

The Top 10

Inside this Special Edition, Expert #31 answers these ten questions. That interview is one of the most valuable parts of the book — so the answers stay in the book.

  1. 01

    If you could give just one piece of advice to someone starting out in this discipline, what would it be?

  2. 02

    What was the biggest challenge you faced in your career, and how did you overcome it?

  3. 03

    What is the most important “Never do this…” rule in your discipline?

  4. 04

    Who inspired or mentored you, and what did you learn from them?

  5. 05

    What is the biggest discovery you wish you had known on day one?

  6. 06

    What do outsiders consistently misunderstand about your discipline?

  7. 07

    What decision looked small at the time but changed everything?

  8. 08

    What skill outside your discipline has contributed most to your success?

  9. 09

    What belief did you hold when you started that you no longer believe today?

  10. 10

    When your career is remembered, what do you hope people say you stood for?

We show the questions so you know what you will find inside. We do not publish the answers here.

What readers will learn

  • How to put the important thing on the calendar first.
  • How to cut work until it can be finished today.
  • How to shut down even when it feels unfinished.
