Fundamentally, and he talks about this, computer programming is a way of encapsulating _your thinking_ in code. You are transferring your thought processes into computer code. A computer program is, quite logically, an encapsulated and packaged thought process.
I don't think anyone can or should try to argue that everyone thinks the same. Hence, not everyone's code is the same. And it follows that some people's thought processes are more efficient or better structured than others. These are the 50x'ers and 100x'ers. The A players. And I feel that just understanding that what you are doing is packaging your thought processes helps immensely in becoming more efficient, just because of the way you approach the problem.
People who are the 50x'ers, or 100x'ers, just solve problems very efficiently and are very good at packaging that problem solving logic in code. They are probably not as good as the 1x'ers in other areas of life--perhaps they are not as good at loving people, or raising children, or writing, whatever. They can be (and in my experience often are) not as good at a million other areas of life, many of which are far more important than programming. But they are very good at problem solving and transferring that problem solving logic into computer code.
I agree with Steve.
