Pietro, the distinction of 'living a life' and 'having a life' is one of a sliding scale of degrees of fortune, privilege, access, desire, and passion, it seems to me. Both Pat and Sean unquestionably have degrees of these but in different quanitites. Maybe even the quantities are sliding in different time periods.
i think you are saying that Pat loves the topic, understands it very well, is passionate and has great access and experience to some of the most elite and exclusive courses, because he is fortunate and he can do so. Sean, pursues the topic to as passionate of a degree and for maybe more practical reasons of fortune and different set of courses to access, looks in the more modest and undiscovered, not so elite fields of play, yet finds the GCA and appreciates it equally with Pat. Either way, these two you've singled out are the real deal when it comes to desire to learn and experience interesting and great GCA, and share their experiences with the rest.
Just my off the top of the head take, even though I only briefly met Pat, and never met Sean. But they sure play a huge role in this site and sharing good GCA observations. I guess one would call them both, generous.
