That's an extremely myopic way of looking at it. Not everything that is done is done solely for the benefit of the one doing it. And I really don't see why you're so committed to generalizing marketing and sales terminology into a general human philosophy, save for your lack of familiarity with the existing, perfectly suitable terminology. More importantly, human identity is complex and multi-faceted, and is not entirely defined by human individuality. I can see myself as an individual, and maybe I'm selling something there, but if I see myself as a living creature, there is nothing for me to sell myself to, since rocks and stars don't give a shit what I'm 'selling.' Humanity itself is not selling anything, and my ability to see myself as an agent of humanity precludes me from selling anything in that role. So anything I do in service of those goals isn't marketing. Imagine you just stubbed your toe. You've just participated in life. Now what are you 'selling' by doing that? Nothing.
