To have any impact in marketing you got to be clear about what you are even talking about.
The problem is: marketing is confusing. People throw around a lot of terms and use certain words, that actually technically mean something else.
They will say they are running an advertisement, when really they are marketing. They will assume that promotion means giving a discount.
They assume that marketing has nothing to do with inside the organization.
If you can't be clear about these fundamental terms - then how could you ever make a huge impact in marketing?
