This is really great advice. My first start-up was seed funded by some 'big-business' people. They told us we had to spend a lot of time writing up business/financial models, including 5-year plans(!?!). As a result, we spent very little time developing and iterating on the actual product. We had a feeling this didn't make much sense, as our idea evolved every day or so, and thus so did the business 'plan'. But we didn't have the confidence or experience to stand up to the people who gave us money. On my current project, we are frequently testing all types of methods and keeping/improving what works. It makes so much more sense.
