The cost of a lukewarm yes

Most calendars do not get ruined by terrible decisions.

They get ruined by reasonable ones.

A coffee that might be useful. A project that sounds interesting. A favour you can probably squeeze in. A trip that would be fun but not quite worth the disruption. A feature that only takes a day, at least in theory.

None of these are obviously bad. That is why they are dangerous.

Derek Sivers has a rule: if it is not a hell yeah, it is a no.

This doesn't work for everything. You cannot run your life by asking whether laundry, taxes, dentist appointments, or hard conversations feel exciting. Some things matter precisely because they are obligations.

But for optional commitments, the rule is useful because it reveals how often we say yes to things that are only mildly alive.

A lukewarm yes feels cheap in the moment. It avoids awkwardness. It keeps the door open. It lets you preserve the flattering identity of being generous, curious, busy, or available.

Then the bill arrives later.

It arrives as a calendar you resent. A project you procrastinate on because you never really wanted it. A weekend with no real rest. A better opportunity you cannot take because your attention is already spoken for.

Annie Duke's book Quit pairs well with the Sivers rule. Quitting is not always failure. Sometimes it is the moment you stop letting past yeses dictate future attention.

The hard part is that quitting on time often feels too early. Saying no at the start can feel rude. Leaving later can feel wasteful. So we keep going until the decision becomes obvious, which usually means we waited too long.

One way around that is to turn a decision into a rule before the invitation arrives. Tim Ferriss has talked about using simple policies like a no-meeting diet or protected blocks of time. The rule does some of the social work for you. You are not rejecting this person, this event, or this one opportunity. You are following a standard you decided on when you were thinking clearly.

I try to treat my own enthusiasm as data. Not the only data, but real data. If something is optional and I keep feeling heavy every time I imagine doing it, that probably means something.

What are you continuing mostly because saying yes was easier than disappointing someone?
Hit reply and tell me. I read every response.

Have a great week!

📚 Book Notes

Quit - Annie Duke

Quit makes the case that quitting is a decision-making skill, not a character flaw.

The line that matters most: quitting on time feels like quitting too early. By the time quitting feels obvious, you may have already spent more time, money, and energy than you needed to.

That is useful for projects, jobs, strategies, habits, and commitments. The real question is not whether something can work if you grind hard enough. It is whether continuing is still the best use of what you have left.

📖 Article

No yes. Either HELL YEAH! or no.

Sivers' rule is blunt on purpose. If every optional thing gets a yes, the things you actually care about have to compete for scraps.

The power of the rule is not that it removes all nuance. It is that it gives you a higher bar for optional commitments.

Opportunity cost
Every yes has a hidden comparison attached to it. The cost includes what you spend and what you can no longer do instead.

A practical companion to the Sivers rule: turn recurring decisions into policies, so every invitation does not require a fresh round of willpower and social negotiation.
