I just read this article about Jay Maisel in Rangefinder Magazine, and found this very interesting paragraph & quote:
'Jay synthesized all the practical experience of his illustrious career into four pieces of solid advice: "First, perseverance trumps talent. Second, do what you want to do, otherwise why bother? Third, be ethical; it might rub off on others. Fourth, don't give up."'
I like it. I found it inspiring enough to put on the fridge.
