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 have this idea that you think is awesome. You want to have that broadest group you possibly can. You don't want to just talk to 1 type of person and learn that, you want to get familiar with the space.

Recording interviews is like magic. a) It stops you from taking notes in the middle and b) you can play that recording for people.

The most interesting things you learn in an interviews come from the: 'interesting', 'tell me more'

People who are using your product and putting up with all these issues, means that they are not actually the biggest problems.

I wish I could tell you the recipe for figuring out who the target user is for your product and who your users should be, but... there isn't a recipe. It comes down to think really hard and use your judgement to figure out who you're really building this for.

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.
