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.

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

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.

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

Who would you talk to? That is the first question for almost any startup that you need to answer. Who is my user and where am I going to find them?

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