By the mandate of your existence, at any given time you do what is best for you in the way that you've learned and currently think is the way that works best for you to do it. This is your function. You cannot deny or escape it. It's happening to you right now. This reflects onto society in a direct function of the impact of each instance of the above in accordance with its true level of influence/impact on that society, considering the feedback of that society upon each instance of function as described above. Organizations do the same except on a larger scale and "once removed" so to speak as in there is a functional, palpable resultant of the the conglomeration of will of the individuals that effects those that interact with it. Hence the world you see before you, exactly how only YOU can see it. Note of interest: Optimally, I think function and purpose are equivalent. Thoughts?
