Four hurdles to jump after starting a business

Those struck me as the four steps you take before you reach your first hurdle.

The hurdles I though the author would note are: Defining a market, building something to address that market, generating revenue from that something and reducing costs/increasing revenue to create sustainable profit from the business.

Well written narratively but not very potent (or relevant to the HN audience generally).

The Cliff Notes version: You need to tell people you're starting a business, believe that it will work out, be prepared unexpected things will happen, and bear in mind there are ups and downs.
