Do you ever stop feeling that sting when a paying customer cancels?

Watching free users bounce didn't bother us much in the beginning because you just assume they weren't your target audience anyway.

But the first time someone pays for your software and then cancels a week later, it feels completely personal. You start digging through logs trying to figure out if it was a missing feature or just a clunky workflow.

Does that initial panic over every single cancellation ever fade away, or do you just get numb to it after a while?
