There is nothing so wonderful that it cannot be ruined by turning it into a youtube channel... The really brilliant people I've met doing things like this always absolutely refused to mediafy their experience. Turning your adventure into a continuous TV show is great way to kill the adventure. We're now so used to everyone running their own shopping channel we don't even notice it. Read Thesiger's books for an account of real experience. The film I urge everyone to watch is Cronenberg's Videodrome - truly the film of our times.
It depends. I find those interesting to watch.
I’ve met some really brilliant people who only finished the challenges they gave themselves because they had a community’s encouragement.
Seems to me you might want to relax your filters a bit and meet some of the other brilliant people.
