If there is such a thing as luck, then I must be the most unlucky fellow in the world. I’ve never once made a lucky strike in all my life. When I get after something I need, I start finding everything in the world I don’t need — one damn thing after another. I find ninety-nine things I don’t need, and then comes number one hundred , and that — at the very last — turns out to be just what I had been looking for.
