>Operations of thought are like cavalry charges in a battle — they are strictly limited in number, they require fresh horses, and must only be made at decisive moments. I love this analogy. People who aren't accustomed to doing long form, extended, in-depth thought about a single problem don't seem to understand this. That your attention and mental effort is a finite resource, that can be frivolously wasted or put to good use. It requires real concerted effort, and it isn't easy. Thus, why most people never really think about anything.
