I suspect that this forum's average reader/poster <peakbagger> has aspirations and achievements exponentially beyond the dreams of your regular couch potato.
So I'd like to see a long running, rich stream of commentary on why we are motivated by special people. Take your time and consider your comment.
Personally, Linus Pauling is my hero, but because he passed away before Al. Gore invented the Internet, I'd like you to consider Burt Rutan's TED
video.
I've followed Burt's achievements for some decades now, I've personally met his brother, also
Jeanna Yeager, and one of his engineers is a best bud.
TED is one of the better reasons for the existence of the Internet.
