I was reading a post on Kindle Boards and came across a reply by Bob Mayer where he quotes Terry Gilliam of Monty Python fame. I loved it and thought I'd pass it on.
Talent is less important in film-making than patience. If you really want your films to say something that you hope is unique, then patience and stamina, thick skin and a kind of stupidity, a mule-like stupidity, is what you really need.Mule-like stupidity ... I can do that! ;)
-- Terry Gilliam.
