A very good article and just fit to understand our efforts in Steemit. The very understanding for me is that work is a process that requires the application of mental or physical effort, which aims to obtain a certain result. It is work, as a rule, that determines the social status of a person. And is, in fact, the main engine of progress in society. Work, as a phenomenon, is inherent only to living organisms and, above all, to man. Thank you @gavvet
