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

The instant they say something you don't expect or already know, you should drop into detective mode.

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

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.

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 question is, once you have this idea, is this enough? Is it something people would actually switch just to have?

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?
