Not the OP, but Google gives me The Everything Parent's Guide to Raising a Gifted Child by Sarah Robbins for the first quote (p125) and Giftedness 101 by Linda Silverman (p87) for the second.

Amusingly enough links to the page with quoted materials in Google Books came as #2 results for both searches. The #1 result points to this thread. I have no idea what the DA uses for SEO but Google just laps it up...
