“In the very beginning, before there are customers, vision is more important than pretty much anything else. But you don’t have to figure out your vision all by yourself. In fact, you probably shouldn’t. Locking yourself alone in a room to create a manifesto of your single, luminous vision looks and feels indistinguishable from completely losing your mind. Get at least one person—but preferably a small group—to bounce ideas off of. Sketch out your mission together. Then fulfill it together.”
