Gelb's most enduring exercise: in a single sitting, without lifting your pen, write out 100 questions. The first 20–30 will be quotidian and generic ('what's the meaning of life'). The middle stretch (roughly 30–60) turns into frustration and complaint ('why does my wrist hurt, why did I pick up this book'). Somewhere past 70 you break through into genuinely new territory as the exercise defeats the habitual mind. You then re-read all 100 and highlight the 10 questions with the most power and pull. Hold those questions in mind just before sleep, keeping a notebook by the bed, because you will wake with insights and 'ahas' — sometimes life-changing ones. The mechanism is momentum: sheer volume exhausts the rehearsed answers and forces the mind somewhere original.
Origin
The exercise appears in Gelb's How to Think Like Leonardo da Vinci and, by his account, has generated more reader mail over the decades than almost anything else in the book.
Core principles
- 01Your first questions are just the habitual mind idling; the good stuff comes later.
- 02Volume and momentum, not polish, break you into new territory.
- 03Your best questions know what you most need to explore.
- 04The subconscious keeps working on a question you seed before sleep.
How to run it
- 1
Set up one unbroken sitting
Take pen and paper and commit to a single session. You can pick a theme, but it isn't required.
Pro tip Don't lift your pen off the paper — the continuous flow is what defeats the habitual mind.
- 2
Write straight through 100 questions
Keep going past the generic opening questions and the frustrated, complaining middle. The breakthrough lives past roughly question 70.
Pro tip Many people carry on to 120 or 150 once they hit new territory.
Watch out If you quit in the frustrated middle stretch you never reach the original material.
- 3
Highlight the ten most powerful
Go back through all your questions and mark the 10 that draw you in and pull at you the most.

Seed them before sleep
Hold the strongest questions in mind before you go to sleep and keep a notebook by the bed to capture the insights you wake with.
Pro tip The subconscious problem-solves overnight; capture the 'aha' immediately on waking before it fades.
In the wild
Gelb reports still getting mail from people worldwide who ran the exercise. The pattern: the early questions are throwaway, the middle is grumbling, and then a handful of late questions land with unexpected force. Sitting with those before sleep, readers wake with insights that, in many cases, reshaped a decision they'd been avoiding.
→ A concrete, sometimes life-altering insight drawn out of the person's own subconscious.
Common mistakes
Stopping in the frustrated middle
Questions 30–60 feel pointless and irritating, which is exactly when most people quit — right before the shift into original territory.
Not capturing the overnight insight
Seeding a question before sleep only pays off if a notebook is ready by the bed; morning ahas evaporate fast.
Is it for you?
Best for
Anyone wanting a simple, repeatable practice to spark creativity, self-insight, or a fresh angle on a problem.
Not ideal for
Situations that need a decisive answer right now rather than better questions.
