The search is never hopeless.

People often ask themselves the right questions. Where they fail is in answering the questions they ask themselves, and even there they do not fail by much. A single avenue of reasoning followed to its logical conclusion would bring them straight home to the truth. But they stop just short of it, over and over again. When they have only to reach out and grasp the idea that would explain everything, they decide that the search is hopeless. The search is never hopeless. There is no haystack so large that the needle in it cannot be found. But it takes time, it takes humility and a serious reason for searching.
― William Maxwell, Time Will Darken It
