Agreeing with both replies to me, I think the secret of my success on the GRE verbal section (twice) was reading a lot for fun. And agreeing with them about correlations between GRE success and life success, I still pursue a lot of personal intellectual interests but have not become notably wealthy, although any middle-class American is wealthy in worldwide terms.
Worth mentioning that my life doesn't correlate to success in any meaningful way, except that I keep making decisions which make me happy if poor.
