You put the "innate" modifier only in front of intelligence, but I suspect, based on both reading and paternal experience, that curiosity, drive, and self-discipline are also tough for parents or teachers to change, and even for people to change themselves through force of will. A recent book I am reading is "Willpower", by Roy F. Baumeister and John Tierney.
