Does your first customer cancellation hit harder than your first 100 signups?

Seeing a massive spike on Product Hunt or Twitter gives you a quick high, but that first cancellation email brings you right back to reality.

It's crazy how you can get dozens of signups in a day and feel fine but one person quitting makes you question the entire business model.

It really forces you to stop looking at traffic and actually check if people are using the app after day three.

For those who've been doing this for a while, does that churn notification ever stop bothering you, or do you just get used to it?
