Well, I have to admit that a big part of what drives me is interest. The more views and the higher the facebook/twitter count, the more I think I am making a difference.
I have 16 more in this series ready to upload.
As for me getting animated: in one of the videos, a guy in the audience had a weird agenda. Rather than ask an on topic question he wanted to push some idea of american
greed on the audience - masked as a question. The question had something to do with the american dream to be a millionaire - can it be done with
permaculture. When I said "yes" he seemed to get ... weird. I'm pretty sure he didn't expect that
answer. So I finally had to insist that as the guy at the front of the room, I get to say
my stuff uninterrupted. I raised the level of animated to get the job done.
