Nathaniel Hawthorne said this quote

Man’s own youth is the world’s youth; at least, he feels as if it were, and imagines that the earth’s granite substance is something not yet hardened, and which he can mould into whatever shape he likes. So it was with Holgrave. He could talk sagely about the world’s old age, but never actually believed what he said; he was a young man still, and therefore looked upon the world—that graybearded and wrinkled profligate, decrepit, without being venerable—as a tender stripling, capable of being improved into all that it ought to be, but scarcely yet had shown the remotest promise of becoming. He had that sense, or inward prophecy, —which a young man had better never have been born than not to have, and a mature man had better die at once than utterly to relinquish,—that we are not doomed to creep on forever in the old bad way, but that, this very now, there are the harbingers abroad of a golden era, to be accomplished in his own lifetime.
