So, as a percentage of the time you spend at work, what percent would you say qualifies as "marketing"? I’m going to count educating yourself, networking, creating products, creating media, spending money, building networks of sneezers, inventing great stuff, executing great stuff, motivating front-line people and telling stories.
The other two choices are:
selling your ideas internally/waiting for approval
dealing with the chaff of responding to inbound junk and wasted time in meetings…
I know some well-paid people who used to be world-class marketers who are now down in the single digits (less than 10%).
