What this article suggests is just one way of starting a startup. It won't work for everyone because for some of us, other's people's problems are only worth solving if the problem also troubles me or the solution somehow deeply interests me. After all, for some the point of starting a startup is not only about business and money, as a software developer I want to build an application I love, and see it appreciated by others by making it a product and profitable business. If you have read Paul Graham's essay, you'd know there's another way, the so called "organic ideas", i.e., to build a product that you love and useful to yourself, then sell it to others who have similar needs. To me this is a better way (albeit riskier), in the end of the day if I fail, I still would have a lot of fun and learnt useful skills, rather than just failed to fill a market gap.
