Had a conversation with a DoP called Mark Adcock (and his writing missus Bryony Ive) today and he said something about overcoming rejection. Always good advice for writers - as blogger Dom Carver says; "It's not the rejection. I can handle the rejection. It's the hope I can't stand." I think we know what he means.
However Mark's advice was an outsider's perspective. He says "As writer's you know that the main character has to go through set backs to reach his goal. It's just the same as that"
Indeed. We all know it has to be like this, to ensure that the payoff is sweeeeet. So enjoy the set backs people!
