I was taught that to create anything you had to believe in failure simply because you had to be prepared to go through an idea without any fear. Failure you learned as I did in art school to be a wonderful thing. It allowed you to get up in the morning and take the pillow off your head.
Concerning God freewill and destiny: Of all that earth has been or yet may be all that vain men imagine or believe or hope can paint or suffering may achieve we descanted.
