The email you drafted at 11pm and shouldn't have sent
It was clear, direct, and absolutely correct. It also cost you the relationship. Being right at midnight is the most expensive form of being right.
A founder I know sent an email to his cofounder at 11:47pm on a Wednesday. The email was three paragraphs long. Every sentence was technically true. He had been rehearsing the points for weeks. The relief of writing it was, he told me later, enormous.
The cofounder read it at 6am Thursday. By Friday afternoon, the cofounder had retained a lawyer.
The email had said something the founder had been correct to think and wrong to send in that form, at that hour, without the eight hours of sleep that would have softened three specific sentences. The cofounder relationship did not survive. The company did, barely. The legal cost exceeded the founder's salary for that year by a multiple.
Late-night communications have a consistent signature. They are clearer than the daylight version, which is the part that fools the sender into hitting send. The clarity is real. The clarity is also the result of having stopped calibrating for the listener — the part of writing that protects the relationship, that hedges the sharpest sentences, that softens the conclusions you would not want repeated back to you in a deposition. Calibration costs tiredness. At 11pm, the founder is tired. The clarity comes for free. The cost shows up Friday.
The rule is small enough to feel insulting. Save the draft. Read it at seven in the morning. Send the version that survives that read. The cost of waiting eight hours is zero. The cost of not waiting is occasionally a relationship you will not be able to repair, a deal you will not be able to close, a hire you will not be able to make.
The trap is that the founder confuses the relief of writing with the wisdom of sending. They are different acts. The first is therapy. The second is communication. Therapy is for the founder. Communication is for the recipient. Conflating them is how messages that should have been written and burned become messages forwarded to lawyers.
If you have drafted an email after 10pm and your finger is on the send button: it can wait. It can always wait. The thing you are afraid will go stale by morning will, in fact, be more accurate by morning. The version that survives until 7am is the version that should exist. The version that doesn't survive is the one you would have spent the next five years regretting.
The send button has no undo. The morning does.
