Well, I don't think that straight A students are smart, especially not in this country where you can be a half-wit and an honor student. However, I do too think a lot more about things than I should, and I find myself regretting it because it just destroys the fun of everything. However, I believe that all people think a lot, so, I guess, thinking a lot is not an official sign of intelligence. Like Jokerman said, if your thinking is wrong, then, how is that intelligence? Personally, I look at intelligence a lot of times from what kind of choices people make. Also, people are only smart because other people are stupid.
