I especially like that the last paragraph in which Julian Stanley summarized why we, as a nation, needs to invest heavily on our gifted and talented kids. Using investment term, "over-weight" rather than "equal-weight".

Julian Stanley said:

"The fact is that the gifted pay off so handsomely for the country," he says. "The work of the world is done by routine people. I don't want to imply they're not crucial, but garbage collectors don't develop new garbage trucks. Those inventions come from talented people, especially those who have had education to develop their talents. Society develops enormously by capitalizing on their talents."
