When I headed to business school, I fully expected to focus on finance, but once I took my first marketing course, I was hooked. I love that there’s a human side to understanding consumers—why people buy what they do. You’re trying to make people happy. I also love the competitive side, looking at how firms compete to win people’s loyalty and preferences. I like the social side in terms of all the public good that we can achieve for non-profits and public policy. Whether it’s advertising or pricing, or how you distribute products, I see marketing as the heart of business. And it changes constantly. - See more at: http://www.tuck.dartmouth.edu/newsroom/articles/brand-champion#sthash.DfCE1nxn.dpuf
