Just one thing
If you remember nothing else from this section remember this:
Marketing is a process driven, deliberate activity.
It is not the events you do, the ads you place, the lovely brand logo you have developed, they are part of it, but they are not it.
Every marketing action has to be a deliberate decision, backed up by processes. Its no good having a great ad campaign, if you dont have the logistics to send out the product, or the people to answer the phone.
Choose what you do, how you look, what you say so it backs up your brand, your story, you business. Marketing needs to be deliberate, it has to be thought out, developed, managed.
