No, I'm being serious. Thinking about your business model is useful, and planning is useful, but the formal practice of writing an official "business plan" (with revenue projections, etc.) is from a bygone era. More than anything, business plans give people (in this case, Arch Grants) a false sense of security.
Oh yes I completely agree. New industries move too fast to predict their profitability. I think the resume will go the way of the business model in our lifetime, if not 10 years.
You nailed it. Doing the traditional resume-and-interview grind is OK if you're just getting started, but as soon as possible you should be building and using your personal network. If after gaining some experience you need a resume to get a job, you're probably doing it wrong.
