Big Deal DUmmies, All the brain power in the world is worthless if you don't know how to use it.
I haven't measured it in years, but my intelligence level allowed me to literally skate in honors level classes all the way through High School. I finished high in my class, but behind a kid that learned how to study. In fact I spent most of my day in class daydreaming about the red headed girl that sat beside me in English.
I failed in college because I didn't know how to study or pay attention. I joined the Army and learned how to study and pay attention the hard way. Now, I average a 4.0 in my college classes and starting my own business again.
My friend, who has an average IQ, has ran his own business since high school. Guess which one of us knew how to study.
