Who you talk to is just as important as what questions you ask and what you pull away from it.

That's actually one of the most disappointing things about doing user interviews and user feedback, which is why I think... people don't do it. You're going to get negative news about your favorite pet feature most of the time.

It's one of the most validating things you can do for a product is go out there and get them to commit to pay you up front.

You want to learn about what's already in their heads. You want to avoid putting things there.

Users think they know what they want, but you get the horseless carriage effect where you're getting asked for a faster horse.

The one question you can't ask is, "Is this feature actually good or not?"

The most common mistakes are showing people your product- don't show them your product, it's sort of like telling them bout a feature.
