"In the book 'The End of Average', Rose, a rising star in the new field of the science of the individual shows that no one is average. Not you. Not your kids. Not your employees.

But while we know people learn and develop in distinctive ways, these unique patterns of behaviors are lost in our schools and businesses which have been designed around the mythical “average person.” This average-size-fits-all model ignores our differences and fails at recognizing talent. It’s time to change it."
