This is a YouTube video titled "Fall in Love With the Problem, Not the Product" (created 2026-10-18T10:30:19Z) containing a short English conversation between Lenny Rachitsky and another speaker about product-market fit. The discussion emphasizes falling in love with the problem rather than the product, expecting multiple pivots, validating ideas with early prototypes, and reading user body language (eyes lighting up, leaning in) as a key early signal of interest.

What's something that might surprise people about what product-market fit looks like?
Usually we try to think about what's the problem we're falling in love with, not the product. Because what I found is it takes 3, 4, 5 pivots before you either got something or you're just like, that's it, didn't work. We talk a lot about how do we get outside the building and just show people prototypes. And when you're showing people early prototypes, what I'm always doing in those is you're looking at people's eyes and like, that is the metric. It is not a DAO, it's not a DAO over a mouse, it's none of that. It's literally like, hey, Lenny, did you see this? What do you think about this? And like, if your eyes kind of light up, if you lean in, these are the kind of signals you're looking for in the early days.
