The human brain is a crazy place, and there are two things that fascinate me most about product and growth marketing. First: the concept of consumer logic and how rational yet irrational it can be. And second: the challenge of communicating in a way that persuades and convinces consumers always requires optimization—so you're optimizing for something that is both rational and irrational.I apply the same thinking in product marketing that I also apply in leadership, because whether you're connecting with consumers or with the team you're working with, you're connecting with the fun irrationality of their logic—in order to bring ideas together, influence an outcome, and also optimize and scale for future growth.
