DD has learned not to tell others how little time it takes her to do so well. That would be rude, given that many of her classmates (3-5y older) are working pretty long hours to get the same A's she does.
I think always liked to know where I stood, intellectually speaking, so if someone could do something much better than me because they were inherently better than me, I would know that it was an unreachable goal (for me).
For example, I didn't get bent out of shape when I *didn't* win the national spelling bee.
I've always thought that it's a good idea to know who is significantly inherently intellectually better than you so that you *don't* compete with them and so that you keep mental lists of people who may be useful in the future if you have specific problems that someone else might be able to solve in a heartbeat.
