This is from Pablo Neruda’s Memoirs.
“The work of writers, I say, has much in common with the work of these Arctic fishermen. The writer has to look for the river, and if he finds it frozen over, he has to drill a hole in the ice. He must have a good deal of patience, weather the cold and the adverse criticism, stand up to ridicule, look for the deep water, cast the proper hook, and after all that work, he pulls out a tiny little fish. So he must fish again, facing the cold, the water, the critic, eventually landing a bigger fish, and another, and another.”
