Particularly: “Miles is one of the most striking characters in science fiction. He is both brilliant (especially in military tactics) and hyperactive; one of his girlfriends describes him as “addicted to adrenaline rushes.” He compulsively and constantly challenges the world in spite of (or because of) his stature: sometimes with disastrous consequences, although more often his mind overcomes his physical weakness.

He has an ambiguous status on his home planet, being simultaneously a pampered and powerful aristocrat and a despised “mutie.” At times he contemplates running away from Barrayar and its prejudice against disabled people, but he never acts on this impulse, perhaps because of his loyalty to his family and his Vor code of honour.”

Certainly a character with characteristics one would want a child to emulate.
