The foreign person I admire most
The reason why I chose Warren Buffet is that first, economy is one of the social concepts that we have to learn, be well aware of, and make good use of.

1. I chose him as when we think of economy, he is the first person that immediately comes to our mind because he can be called the person who is at the height of economy.
2. I chose him as when we think of economy, he is the first person that immediately comes to our mind enough to be called the person who is at the height of economy

Which is better? Does 1 sound natural? I think "enough to be called" doesn't fit there. How can I change it?
