Most people treat the calendar as something done to them — a mess that tells them what they have to do. Design Your Day flips it into a canvas: you draw out the day you intend, including non-work blocks, set it to repeat, and then compare intention against reality each day. The gap between them is the whole point. You iterate the template Groundhog Day-style, getting a little better at the day each time, being kind to yourself about the parts that didn't work.
Origin
A named tactic in Make Time by Knapp and Zeratsky. Knapp explicitly frames the iteration philosophy via the film Groundhog Day. Lenny notes the same 'calendar as to-do list' principle from previous guest Nir Eyal, indicating convergent thinking rather than a single origin.
Core principles
- 01Your calendar is a canvas for design, not a queue of demands.
- 02Blocking non-work items (wake, exercise, breakfast, shower, dog walk) reveals how long things actually take.
- 03The mismatch between planned and actual is information, not failure.
- 04A repeating template gives you many attempts at the same day.
- 05A blocked calendar also defends the time from other people booking it.
- 06Teams can share a template — buckets for meeting-types and reserved solo focus blocks.
How to run it
- 1
Draw the day you want, everything in it
Block out the whole day on the calendar, not just work: when you wake, exercise, eat breakfast, shower, walk the dog, plus your Highlight focus block and specific work items ('work on next week's newsletter post', 'prep for the podcast').
Pro tip Be specific rather than generic — 'focus time' is weaker than the named piece of work that goes in it.
- 2
Set it to repeat
Make the day a repeating template so you get to run the same experiment again tomorrow instead of designing from scratch each morning.

Compare intention to reality
At the end of the day, look at what you planned versus what actually happened and how long things actually took. Expect the estimates to be wrong the first time.
Pro tip Visual learners get outsized value here — seeing the day laid out is what makes the drift obvious.
- 4
Adjust the template, not your self-esteem
Move blocks based on what you learned. If mornings turned out to be bad focus time, try moving the block to the afternoon. Be kinder to yourself on the parts that consistently overrun.
Pro tip Knapp's frame: it's like debugging code — you can see the line where the bug happened, so just fix that line.
Watch out Don't repeat an identical failing template out of stubbornness. The point of Groundhog Day is that he gets better at the day.

Let the blocks defend themselves
A visibly full calendar stops colleagues booking over your focus time. The default politeness of saying yes to any free slot is what quietly destroys your own priorities.
Pro tip Extend to the team level: shared time buckets for types of activity, with certain windows reserved as protected solo work for everyone.
In the wild
He runs a weekly template rather than an ad-hoc calendar: Monday, Wednesday and Thursday mornings are focus time; Tuesday and Friday mornings are meetings. The first half of the day before lunch is defended very intensely.
→ As a VC — an environment he describes as natively the busy bandwagon — he still ships books, launches and portfolio sprints, which he considers the firm's edge.
Switching calendar tools, Knapp scheduled literally everything — wake, exercise, breakfast, shower, dog feeding — and set it to repeat. Within a week he found that how long he thought things took was not how long they actually took.
→ He adjusted the template rather than his self-image, and started testing whether his focus block should move out of the morning entirely.
Common mistakes
Treating the calendar as something done to you
Most people hate their calendar and fantasize about living without one. That posture guarantees the defaults win — the calendar fills with other people's priorities because you never claimed it.
Beating yourself up over the plan-vs-actual gap
Knapp's older frame was 'I'm screwing up, what can I fix' — a head space he says was not productive. Groundhog Day reframes the gap as another attempt, which is what makes the iteration sustainable.
Leaving free slots as an open invitation
An empty calendar slot reads as availability. The default to be helpful and say yes to anything dropped into a free slot defeats your own priorities before the day even starts.
Is it for you?
Best for
People with nominal calendar control whose focus time keeps getting eaten by others' bookings and their own bad time estimates
Not ideal for
Highly reactive or shift-based roles where the day is externally sequenced and blocking has no authority behind it
From the transcript
“there's a tactic in the book called design your day that is really about kind of drawing out”
“your your day and using your calendar as a canvas where you can design how you want to spend your time rather than using your…”
“so I can adjust it I can adjust the template”
“it also keeps someone else from booking that time double win”
