How can I?

How can I think about one day writing something, when everything seems to have already been said in the best possible way?

"There is so much weariness and disappointment in travel that people have to open up — in railway trains, over a fire, on the decks of steamers, and in the palm courts of hotels on a rainy day. They have to pass the time somehow, and they can pass it only with themselves. Like the characters in Chekhov they have no reserves — you learn the most intimate secrets. You get an impression of a world peopled by eccentrics, of odd professions, almost incredible stupidities, and, to balance them, amazing endurances." - Graham Greene
