One of the best things about this book is the introductory chapter where Tim describes lessons learned in asking good questions over the years.

These lessons include:

• Sequencing of the questions for maximum impact.
• Starting with simpler questions as a warm up for the brain. This is no different than warming up before a workout.
• How and when to best approach busy people to get questions answered.

The ability to ask good questions is extremely valuable for building great projects and professional development.
