Compounding, not accumulating複合，而非累積
A note on why some people grow exponentially sharper over time — and most of us don't.一則筆記：為何有些人隨時間變得越來越敏銳，而多數人不會。
Most of us treat learning like a savings account. We make deposits — a book here, a course there — and trust the balance climbs. It does climb. Just slowly, and in a straight line.
The more interesting question isn’t how much you deposit. It’s what happens between deposits — whether each new idea can find the others already in the room, and multiply against them.
Addition has a ceiling
When knowledge only accumulates, every field stays in its own column. Finance over here, design over there, a little mathematics in the corner. Useful, tidy, and ultimately limited by how many columns one person can keep.
Multiplication breaks the columns. A habit borrowed from markets reshapes how you read a piece of music; a structure from music clarifies a data model. Each field becomes a lens for the others, and the returns stop being linear.
Knowledge added together grows. Knowledge multiplied compounds — and takes on a form no single field could hold alone.
That is the whole wager of HtPi: point the same habits of mind — distil, recompose, compound — at everything, and let the interest accrue.
多數人把學習當成儲蓄帳戶：讀一本書、上一門課，存進去，相信餘額會漲。它確實會漲——只是緩慢，而且是一條直線。
更有意思的問題，不在於你存了多少，而在於每次存入之間發生了什麼——新的想法，能不能找到屋裡原有的其他想法，彼此相乘。
相加，是有上限的
當知識只是累積，每個領域都待在自己的欄位裡：金融在這邊，設計在那邊，數學蜷在角落。有用、整齊，最終受限於一個人能維持多少個欄位。
相乘，會打破欄位。一個來自市場的習慣，重塑你聆聽音樂的方式；一個來自音樂的結構，理清一個數據模型。每個領域都成為理解其他領域的透鏡，回報不再是線性的。
相加的知識會增長；相乘的知識會複合——並成形為任何單一領域都無法獨自承載的樣貌。
這正是 HtPi 的賭注：把同樣的思維習慣——提煉、重組、複合——指向一切，讓利息自然累積。
