The lean startup approach for building a startup is to rapidly make a prototype, get the prototype out there in the world as fast as possible and get feedback on whether people actually are interested. But I would say that there's also a huge pitfall and it relates to the ideas that you were talking about. It's very easy to get stuck on just lots of experimentation and not really iterating and trying to really find that blockbuster. You made me think about, you know, Amazon has this day one philosophy. So they had their minimum viable products but now they're doing so much more.
