As marketers we each have a unique set of circumstances in which we operate.  We sell products and services to business and consumer markets.  Keeping up with changes, best practices and processes is critical to the success of our efforts.  Conferences, online education, trade magazines, blogs, social networks all provide essential resources, providing those of us that care, access to the latest information.  Nevertheless at the center of any marketing program is the product, and in my book there is no product more difficult than, well, water.  Imagine, selling a product that is readily available for free just about everywhere, it is almost like selling air (oh, that is done also).  Kudos to those marketers that sell water, I have to put them on the top of the eMarketing list.
