About this quote

Loose, drunken promises often force you into choices you never intended. The line points out a simple correction: let your sober judgment set the terms, not a few drinks and bravado. If you find yourself stuck because of something said in a blur, take clear action—apologize, set boundaries, or honestly renegotiate. Treat it like data: what you promised while impaired tells you where to close your mouth next time.

When to use it

• After the office holiday party your teammate says they’ll lead the risky client pitch; the next morning you ask, “Do you really mean that when you’re sober?”
• Your brother drunkenly vows to buy Mom a new car; you text him Hemingway’s line and say, “Decide before you put down your card.”
• At a reunion someone boasts they’ll run a marathon on a dare; you answer, “Okay—Hemingway says do it sober, so start training this week.”
• A friend promises to invest their bonus in your startup after a night out; you tell them, “Don’t commit like that. Confirm it when you’re sober.”
