Chris Dixon claims in a tweet: "influx of new entrepreneurs: startups are a career, not a one off. plan to stick around when startups aren't cool again and you'll do well."
While I'm sure he means well, I reject his fundamental hypothesis. Startups are not a career. In fact, startups are merely a way to prove hypotheses. Even the so-called 'startup types' or 'serial entrepreneurs' are known not for the many startups in their careers, but for the companies that are no longer startups – that graduated to becoming 'real companies'.
In other words, the entrepreneurs I respect are Steve Jobs, Bill Gates, David Filo and Sergey Brin – not the ones that have resumes that read – "Founded 5+ companies with 2+ exits in 2 years"
What about you?
