When I think about marketing as a practice, I think about matching products/services with needs. We spend a TON of time on the four P’s (product, price, promotion, place) but they’re only as good as our understanding of the customers needs.
You could have the best product, price, promotion and placement, but if it doesn’t meet a need, it’s going to fall flat.
So in answering your question I would have up and coming marketers focus on understanding their customers needs through research. If you know how to elicit thoughts, fears and emotions from people in conversation, you’re then in a commanding position to reflect that in your marketing.
