playing field：年轻人和没有经验的人可以做这件事情，年长和有经验的人也可以干哦。poor and unknown are actually huge assets when it comes to starting a startup.
why you should start a start up
不要为了创业而创业
有很多事情可以赚大钱，并不是只有创业
无法想象有多难
只有被某一问题所驱使才去创业，为了解决某一问题。来开创一个公司去解决这个问题。
Idea
流言：idea不重要。
Fact: 花很多时间在一个很low的idea那样并不cool。好的执行力加上一个坏的idea，你什么也玩不成。
Definition：it includes the size and the growth of the market, the growth strategy for the company, the defensibility strategy and so on. When you evaluating the idea you need to think through all these things, not just product.
TheIdeacomes first, the startup should come second.
公司应该是mission-oriented
你无法的到团队成员的高度注意力和责任感，除非他们觉得这是一个important mission。
4到10年才会有成果。如果你不爱你的idea你很可能会半途而废。
Good starts take ten years.
别的公司的人会更愿意帮助你。
好的idea初始看起来有可能是非常糟糕的
eg. the 13th search engine & Facebook
these all sounded really bad, but they turned out to be good. If they sound really good, there would have been too many people working on them.
垄断
很多人都想让自己的idea在市场上获得垄断，但获得垄断很不容易，会有很多的竞争。 先吸引一小部分市场，再扩张，获得垄断。
How the market evolve
常见错误：只想着自己公司的发展，而没有想市场的发展。
Why now？
为什么是现在实行这个点子，而不是早几年或是晚几年？
From 50 Cent: Most people think first of what they want to express or make, then find the audience for their idea. You must work the opposite angle, thinking first of the public. You need to keep your focus on their changing needs, the trends that are washing through them. Beginning with their demand, you create the appropriate supply.
Product
Great Idea > Great product > Great Company
创业者总是要坐在电脑前埋头苦干于他们的产品，与他们的客户交流。
Your Job
Build something users love
talk to users
先有小部分人Love，发展到大部分人喜欢？不太明白
先找到1小部分人真的真的很爱用你的东西。
很少创业公司死于竞争，而是死于他们不能给用户想要的东西。
Great products win
Make something users love
Simple is good.
刚开始的时候不需要去买google的广告你来开发潜在的客户，你只需要一小部分客户，这些人会给你feedback。
Ben Silverman, when everyone thougt Pinterest was a joke recruited the initial Pinterest users by tagging up strangers in coffee shops. They said will you please use my product. He also used to run around the Apple Store in Palo Alto. He will set the browser the Pinterest home page real quick before they caught him and kick him out.
