Yes of course, all the time. When I've done something I think is pretty good, the first thing I do is look around for someone to agree with me. Actually, if I persist in pushing my point of view or yakking about what I've done, I see eyes glassing over. That tells me to 'get over myself" and my puny achievements and start working on the big problems of the world.
People are bascially selfish and there's nothing wrong with that, survival is a built in quality. But if they manage to get over them selves and their narrower views, they're in for an enlightenment and a renewed sense of purpose. Our talents are to be used for mankind and not simply to make us feel better about ourself.
I am not necessarily speaking for Miss Barbie Girl but am simply answering a question as if it's asked of everyone, as it should be.
