Excellent definition of "marketing" #3

"Marketing is everything you do to promote your business, from
the moment you conceive of it to the point at which customers
buy your product or service and begin to patronize your business
on a regular basis. The key words to remember are everything and
regular basis."

My favourite marketing guru Jay Conrad Levinson from Guerrilla Marketing.

NB: I believe every marketer and business owner should have a well thumbed copy of this book in their office.
