“Any framework, method, or label you impose on yourself is just as likely to be a limitation as an opening.” - Rick Rubin
All marketing ideas and frameworks are models. Models of how the world works. Models of economics. Models of what motivates people to purchase art.
There is something important you must understand: All models are wrong.
Even our scientific models are wrong. Einstein’s theory of relativity and quantum mechanics are wrong. They are each only “right” in a subset of reality and they contradict one another. Science will never know the Truth (with a capital T), but will, over time, continue to develop new models that are slightly closer to Truth. “Trust the science” is a popular phrase, but it embodies the opposite ethos of what real scientists actually do.
It’s the same with marketing advice.
