Anyone who thinks there is a clear and universally accepted definition lacks the understanding of what intelligence truly is. Academics may not define one's intelligence, however, they are a definite sign of an existing intelligence. For instance, the person may not have been able to slack off in class and get decent grades because of good test scores, yet they possessed the intelligence to realize what it would take for them to achieve what they did.

For me, intelligence is the ability to ultimately realize and utilize your abilities to maximize your quality of life. Think of the playboy bunnies... Do you truly think they are unintelligent? They have realized a career path that has allowed them an amazing quality of life while many mislead individuals believe THEY are the intelligent ones for becoming a desk jockey. Which would you choose? Workaholic desk jockey for mediocre pay, or ditsy girl who gets paid the same (or even less money) to do what they do best, and have the freedom they have?

Some people are good at the desk jockey type job, don't get me wrong. But if you think that only billionaires and executive workaholics are the only intelligent ones in the world, you MAY not be so intelligent yourself. In fact, I would rather be poor and enjoy life than work all day everyday for huge amounts of money to spend on things I wont have time to enjoy.
