The Bible says: "Prov 2:6 For the LORD giveth wisdom: out of his mouth cometh knowledge and understanding. He layeth up sound wisdom for the righteous. "
In high school I remember those who managed to score a 1000 or more on the SAT's and thought they were "smart". Unfortunately, some of those same people failed at life. Either they couldn't make it in the workplace or their marriages fell apart. Don't misunderstand, many of the "smart" ones did do well, but shouldn't all of them have succeeded in every aspect of their life?
Part of the problem is that we live in a society where financial gain and the accumulation of possessions is considered paramount. Many people who do not know God seem to be successful, but without God in their lives that success is but an illusion. Success is more than just getting "things" and being "happy" it is in living a life guided by the maker of the universe. Without HIM our efforts will eventually turn to dust. Be wise, seek God; it is the smart thing to do.
