投入時間與心力
把「放進去的東西」從錢換成時間、力氣和感情，形狀完全沒變：你先付出，回報要等後面。因為東西已經放進去了，這個字也就帶著「拿不回來就虧了」的重量。

To use a lot of time, effort, or money on something because you really want it to succeed.

核心畫面
Picture money you deliberately do not spend today: you hand it over to a business, a flat, some shares — and you leave it sitting there. It has not gone; it is parked inside something so that it can grow, and you expect to get it back later, bigger. Invest always has that shape: something valuable goes in now, and the return comes afterwards.

可以想成一筆錢你今天刻意不花掉：你把它交給一間公司、一間房子、一些股票，然後就讓它待在那裡。這不是「花掉就沒了」，而是「停在裡面等它長大」，之後再拿回來，而且希望拿回來的比放進去的多。invest 的每一個用法都有這個形狀：有價值的東西先放進去，回報在後面。From the word’s history
'Invest' entered English in the late 14th century meaning 'to clothe someone in the robes of an office', from Latin investire 'to clothe in, cover, surround' (in- 'in' + vestire 'to dress' — the same root as vest). The money sense is attested from the 1610s in the East Indies trade, probably taken from Italian investire, on the idea of giving your capital a new form the way robes give a person one.
invest 在 14 世紀末進入英文時的意思是「為某人穿上官職的袍服」，來自拉丁文 investire「給…穿上、包覆」（in-「進入」＋ vestire「穿衣」，和 vest 背心同源）。金錢的用法從 1610 年代的東印度貿易開始有紀錄，可能是從義大利文 investire 借來的，取的是「把資本換上一個新的形體」這個想法——就像袍服讓一個人換上新的身分。
