節錄第一段序言，相信有在新創產業待過的人一定會懂 Sam 想講什麼：
Your goal as a startup is to make something users love. If you do that, then you have to figure out how to get a lot more users. But this first part is critical—think about the really successful companies of today. They all started with a product that their early users loved so much they told other people about it. If you fail to do this, you will fail. If you deceive yourself and think your users love your product when they don’t, you will still fail.
The startup graveyard is littered with people who thought they could skip this step.
It’s much better to first make a product a small number of users love than a product that a large number of users like. Even though the total amount of positive feeling is the same, it’s much easier to get more users than to go from like to love.
