I have been taking Marketing classes it is the study of management of exchange relationships.
I took a bunch when I went to school for business. Do you think they will be useful? 
Well marketing teaches you how to keep and satisfy the customer. So of course it will be useful 
Haha, you would think so until you get out of school and realize. Either you have it or you don't. 
Yeah I read that Marketing is it can be concluded that Marketing is one of the premier components of Business Management.
I thought it was a waste of money. The best marketers are people who love people and know how to close a deal. That can not be taught. 
Well the exact definition of Marketing is "the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large.""
Can't marketing be self taught, why take classes?
