Intelligence is a lot like height. The world is designed for people of a certain level. If you're far below that, you're going to struggle. If you meet a certain threshold, you'll be fine. And if you're far above, it may give you a slight boost, but is not going to magically propel you to success. You can do math in your head? Okay, your competitor will just use a calculator. You have impeccable spatial reasoning? Okay, the other guy will just draw himself a visual diagram. There are only a few narrow domains where the raw processing power of your brain is going to automatically cause you to become richer or more successful than your peers. For everything else, luck, people skills, creativity and hard work are the dominant factors (in roughly that order).
