The most personal detail may be the one you nearly removed to seem more universal.

Sanding a piece down to make it relatable makes it relatable to nobody. The specific detail feels too much like yours, too odd, too small to matter, so out it goes in favor of something broader that anyone could have written. But recognition comes through particulars: the brand, the wrong word your family uses, the smell of that hallway. General statements are agreed with; specific ones are felt.

Go back through the last thing you made and find what you cut for being too personal. Put one of those pieces back in and see whether it improves. Strangers tend to connect through the details you thought only you would understand.
