A decision heuristic for protecting focus and energy against commitments that feel safe because they're months away. You collapse the psychological distance by asking how you'd feel if the obligation were tomorrow, and back it with a standing personal 'policy' that makes declining guilt-free.
Origin
Susan Cain's practice, reinforced by psychologist Mihaly Csikszentmihalyi's account (in his book 'Flow') of famously creative people who declined studies to protect their creative work; and by Naval Ravikant's warning about success crowding out the work that created it.
Core principles
- 01We say yes to distant asks because they feel safely far away
- 02The true test is how you'd feel doing it tomorrow
- 03Every accepted obligation trades against the deep work that created your success
- 04A pre-declared personal policy makes saying no easy and guilt-free
How to run it
- 1
Apply the tomorrow test
When asked to do something months away, before saying yes ask how you'd feel if you had to do it tomorrow or next week. That reaction is the real signal.
Pro tip Pair it with a body check — 'what is my body saying?' A gut 'no' that produces relief when the thing doesn't happen confirms the decline.
Watch out Distant commitments feel deceptively safe; the calendar distance, not the task, is doing the persuading.

Separate the goal from what reaching it requires
Distinguish the outcome you want from the daily life required to get it. Ask 'do I want to wake up every morning doing what it takes to reach this goal?'
Pro tip You can love a goal (e.g., running a company) yet rightly decline it because you'd hate the daily reality (e.g., managing a team every day).

Adopt a standing default-no policy
Create an explicit personal policy (e.g., default no to events, talks, other podcasts) and break it only rarely and strategically. Telling people 'I have this policy' makes declining easy.
Pro tip Cain limits company/school speaking; Lenny runs a near-total default-no, breaking it ~5% of the time — a policy removes the case-by-case guilt.
Watch out A blanket no forfeits genuinely meaningful encounters, so keep a small deliberate allowance rather than an absolute ban.
In the wild
When Csikszentmihalyi approached famously creative people to study them, some declined, saying that if they said yes to such things they wouldn't be able to do their creative work.
→ The refusal-to-protect-the-work principle stuck with Cain, who now invokes it whenever she regretfully says no.
Lenny created a self-imposed policy of no events, talks, or other podcasts by default, breaking it only ~5% of the time for work or close friends.
→ Protects his deep newsletter work from the 'oh that'll be fun' drift that would otherwise fill his calendar.
Common mistakes
Saying yes because it's far away
Distant asks feel costless and get accepted reflexively; when the date arrives you resent the obligation you could have declined.
Chasing a goal whose daily grind you'd hate
Wanting the outcome isn't enough; if you wouldn't enjoy the day-to-day required to reach it, pursuing it costs you your life quality.
Is it for you?
Best for
Focused makers (writers, researchers, solo creators) whose success invites energy-draining obligations
Not ideal for
Early-career people who still benefit from broad exposure and serendipitous meetings
From the transcript
“when someone asks you to do something that is like three or four or five months away there's a tendency to say yes to that…”
“if I said yes to these kinds of things I wouldn't do my cre I wouldn't be able to do the Creative work that I…”
“I actually created a policy with myself uh no events no talks no other podcast just like the default is no”
“that question of do I want to wake up in the morning doing what it takes to reach that goal is really big one”
