The way that I approached numbers, think about them, the same as for language as well-acquiring vocabulary, understanding the grammar, the structures of languages, the rhythm, the music and so-on - these things obviously evolved.

I know from my own experience that there is much more to 'intelligence' than an IQ number. In fact, I hesitate to believe that any system could really reflect the complexity and uniqueness of one person's mind, or meaningfully describe the nature of his or her potential.

I feel traveling certainly does broaden the mind. In my case certainly I feel more confident. It gives you a new perspective on the world.

Our thoughts and our feelings, of course, are not wholly objective, they're inherently subjective. And that's the danger, and I think as long as we're aware of it and can push back against it, I don't think that these two views are necessarily incompatible.
