If you just talk to who's easy to talk to, you're not really getting the best data.

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

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.

Sales is this cure all for this problem. Get people to give you their credit card and I guarantee you they're actually interested.

People don't like silence, so they'll keep talking to fill the void.

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