This is Seth Godin.

"What we're actually looking for often when we go to see somebody for advice is not for them to change our mind, but for us to change their mind."

"The alternative is to shun the non-believers. To address the smallest viable audience. Viable, because if it's not big enough or eager enough, it's not worth the journey. But smallest. Because if we act like we only can serve a few people, it will require us to focus obsessively on those people"

“Change is not a threat, it’s an opportunity. Survival is not the goal, transformative success is.”
