"Running a startup is a great way to learn how to, and how not to, ignore the right things."

If attention is the most valuable commodity, our most valued asset, it may be said that the most valuable personal skill to be effective these days is ignorance, literally ignore-ance -- the ability to selectively and appropriately ignore that which is irrelevant or merely distracting. In this context, ignorance is not bliss -- it is the practical manifestation of acute awareness and heightened perception.
Bad advice.
I think some people use a strategy like: "Be good enough to eventually win over your competitors, but not good enough that they'll see you coming and decide to get serious at competing with you". I could see that happening at a startup trying to take control of a "secret niche".
I think that's an horrible strategy, it's like a glass ceiling artifically limiting your growth and progress.
