Did you watch the video? He appears to have dropped everything to train for the event. What more could he possibly do?
In case you are 22, let me tell you that at 35 he can't say "I'll train for five or ten years" - that training would be offset by his natural physical decline, and an increase in injuries.
I did watch the video, and no, I am not 22. I certainly would be more prone to agree that he's trying his best to make a documentary film. Simply 'dropping everything' to work on something doesn't automatically imply you're doing your best or even attempting to do so.
