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?

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 crucial people to get your product started for the first 6 months are not who will be using it 3 years later.

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

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

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

The pool of people you care about is going to shift over time.
