To my shame, you are correct, the quote is nowhere to be found. It’s not either from Paul Graham. I thought it was a famous quote & concept among us entrepreneurs…

I vividly remember a blog from Joel saying things along Why are entrepreneurs passionate for things that seem very niche? / The truth is, once they succeed, they become passionate / So we have a bias of selection when assuming that all entrepreneurs are passionate about their product.

But this post is nowhere to be found. I thought the quote was the title of that blog post.

I have to make amend and recognize that I might be senile and spreading a false quote. Thank you for waking me up.
