The IQ is very one-dimensional.
There is no sure way measure intelligence. Most IQ tests have a bunch of questions that basically ask,"How much do you know?"
Don't get me wrong, some of the questions are puzzles in which you have to use common sense and strategy, but most of them just ask questions like,"Who is the current prime minister of England?" or something like that and if you get the question right, you score higher.
Plus, like the article says, your level of intelligence doesn't have much to do with your success. Take me for example, I was a horrible student in high school, yet my IQ score was measured between 146 and 150. The work was in no way hard for me, but I just didn't want to go to school. In fact, if had gone to school half as much as I did, I could've maintained a 3.5 GPA, but I was lazy.
Intelligence means nothing if you don't have the perseverance and the will to succeed. My mother always told me,"Success is 1 percent inspiration and 99 percent perspiration." I wish I had listened better back in high school, then I might have done better.
Being in college now, I can take her advice. Success is not a question of whether you can or cannot, it's a question of whether you will or won't. It doesn't matter how smart you are, if you don't have the means to succeed in life, then you never will.
