Same joke, half a second early, and nobody laughs. Timing is half of everything.

Content and delivery are not separable in the way you would like them to be. A good idea arriving at the wrong moment is received as a bad idea, and the failure gets filed under quality when it belonged to timing. That is why something that fell flat once can work perfectly a month later with nothing about it changed.

When something of yours does not land, check the moment before you rewrite the substance. Ask whether people were in any condition to receive it. Try again in a better window before concluding it was wrong.
