I have written not so long ago about answering for my home state- being an ambassador of sorts. Something not entirely unlike that has begun to happen in connection with other affiliations of mine. Like anyone, as I have lived I have accrued experience with certain things over time, and they have come to partly define me. For a long time, the nature of social networks of which I was a part meant that nothing really became of any mastery or authoritative knowledge I may have possessed of things like Boy Scouts or other things I was up to in those days. I never really had multiple networks of contacts exactly, so there was no other group of people in my life entirely unrelated to the thing that was predominant for me at any given time.
That's changed now, and the diverse makeup of my friends, acquaintances and well-wishers is such that any one thing I'm heavily into may indeed be unknown to a substantial portion of people in my life. I, without any motives or agenda other than sharing my enthusiasm, have organically discussed those things. This has been just because I have enjoyed them. Evidently my joy and overall apparent prosperity in life have done a sales job that I never thought I would be capable of with a conscious effort.
