How to Plan Your Day Like a CEO: Strategies for Prioritization and Focus

I have been the person a team was waiting on, with a calendar that looked like
a spreadsheet had been dropped from height. The productivity literature told me
CEOs solve this with five a.m. starts and ninety-minute blocks. What actually
solved it was smaller and less impressive, and it matches what the research on
executive time use says rather than the myth.

What CEOs actually do with their time

The largest study of executive time use tracked over a thousand CEOs across
six countries, hour by hour. The ones running better-performing firms did not
have fuller calendars. They spent more time in planned, multi-function
meetings with their own senior people and less time reacting to whatever
arrived; the difference was between running the firm and being run by it
^[1]. Nobody in the data succeeded by planning every
minute. They succeeded by deciding what the few important hours were for and
protecting them.

That is a more useful model than the poster, and it happens to be the only one
compatible with an ADHD brain.

Why the poster version fails ADHD brains

Minute-by-minute schedules assume you can estimate durations; everyone
underestimates them, and the planning fallacy holds up even in people who know about it ^[2]. People with ADHD estimate worse and
experience time as now and not-now, so a 14:15 block does not exert pressure
until it is 14:15 ^[3]. Rigid plans fail
rigidly: one slipped block becomes an afternoon of guilt, and guilt is what
turns the next task into something to avoid ^[4].

The method

Decide tonight, not this morning. The evening brain, on medication or at
least awake, is the one that should choose tomorrow’s priority. Write one
sentence: the single thing that, if it is the only thing done, makes tomorrow a
success. That sentence, plus its first physical action, on a card. The if-then
form - “when I sit down at nine, I open the doc and write the summary” - is
among the most reliable ways to convert intention into action
^[5].

One priority, three at most. The Eisenhower matrix is the tool everyone
cites for this. Eisenhower himself was quoting someone else, and it was Covey
who turned the urgent-important grid into a method ^[6];
its value is not the grid but the question it forces: what here is important
and not urgent, because that is what never gets done otherwise. Put that in
the card.

Protect two blocks, not the whole day. Ninety minutes each, calendar
entries with a name, treated like meetings with someone you cannot cancel on.
Everything else in the day is allowed to be chaos. The brain needs fifteen
uninterrupted minutes to lock on, and an interruption costs more than twenty to
recover from ^[7]; two blocks that actually hold
beat eight that get invaded.

Batch the reactive work into a window. Messages, reviews, small decisions:
one or two fixed windows, not a background process. Inside the window, do the
two-minute things immediately; outside it, write them down. Every switch out of
the block leaves residue on what you were doing
^[8].

Add half again to every estimate. Not because you are slow, because you
are human, and slightly more so. Buffers between blocks are where the day
absorbs reality.

Delegate the decision, not just the task. The CEO study’s biggest finding was about multiplication: time spent making other people able to decide compounds,
time spent deciding for them does not. As a manager with ADHD this was the
change that gave me my calendar back. A decision-rights map - who decides
what, written down - removed a whole class of interruptions.

Review for ten minutes, once a week. Not planning. Looking: which blocks
held, what the one-sentence priority was each day, whether it got done. The
pattern after a month tells you more about your actual working rhythm than any
productivity book.

What it looks like

My card for tomorrow, as I write this, says: “Review draft of the org design
doc - open it, read the summary, write three comments.” Two blocks in the
calendar, one at ten, one at two. A message window at eleven-thirty and one at
four. That is the whole plan. It survives a bad morning because there is
almost nothing in it to break.

Try this: tonight, write tomorrow’s one sentence and its first action.
Book one ninety-minute block and defend it. Tomorrow evening, note whether the
sentence got done. Do that for five days before adding anything - most people
discover the one block was the entire method.
