寫這個的源起是因在看行業分析的時候come across。覺得這條法則對自己有諸多用處，多家留心可以糾正自己的很多分析框架的問題。
I think it’s important to reason from first principles rather than by analogy.
The normal way we conduct our lives is we reason by analogy.
[With analogy] we are doing this because it’s like something else that was done, or it is like what other people are doing.
[With first principles] you boil things down to the most fundamental truths…and then reason up from there.
--Elon Musk
“我在想存在一種好的思維框架（a good framework for thinking）,那是物理學的東西，你知道，有點兒像第一原理推理（first principles reasoning），總體來講，我認為存在…將事情縮減至其根本實質，并從那里開始向上理論，和類推推理剛好相反?！?/p>
