goals or constraints are just different life outlooks, and could be rephrased and characterised as overly ambitious and giving up depending on which finger was pointing where as to the worlds complexity, that realy depends on definitions, and how much situational detail is included in "different" so called profesions, which to illustrate I will point out that, no one who has not taken on formal(paid) students and actualy proffesed there occupation is in fact a profesional. my real point is that any discussion of the things that are exclusivly human constructs is stuck in a world of arbitrary definitions and is meaningless unless there is a strict adhearance to those defintions. there are dictionarys, use them
