> girls are praised for results and boys for effort

This is a sad thing, if true. If true, it does sound very changeable. From the article you linked:

> bright girls believe that their abilities are innate and unchangeable, while bright boys believe that they can develop ability through effort and practice.

Everyone should learn somehow that effort and practice bring about change in behavior and improvement in skill level. It's the only thing that has brought me much level of success, other than birth.
