Summary - When: The scientific Secrets of Perfect Timing

Author: Daniel H. Pink

When BookWhen: The Scientific Secrets of Perfect Timing by Daniel H. Pink explores how timing can impact our lives and how to use it to be more efficient and productive. The book uses research from psychology, biology, and economics to help people succeed at work, school, and home. 

Pink argues that timing is a science, not an art, and that people experience a regular pattern of peak, trough, and rebound throughout the day. Some insights from the book include:

  • Morning: People are more energized and positive, and analytic tasks are performed better
  • Afternoon: People experience a trough, and innovation and creativity are higher
  • Evening: People rebound
  • Beginnings: Are more important than we realize
  • Naps: Should be between 10 and 20 minutes to combat sleep inertia
  • Choral singing: Is as good for you as exercise 

The book covers topics such as:

  • The timing of day, year, and project
  • Beginnings
  • Midpoint
  • Endings
  • Chronobiology 

Each chapter ends with a "time hacker's cheat sheet" with practical takeaways.
