“思想的巨人，行動的矮子”說的是那些有各種宏大想法，卻很少去實踐的人。在英語里，我們說一個人有很多ideas，但是都不付諸實踐，于是他們就欠了這些ideas很多債，于是就有了idea debt這個說法。

Idea debt is when you spend too much time picturing what a project is going to be like, too much time thinking about how awesome it will be to have this thing done and in the world, too much time imagining how cool you will look, how in demand you’ll be, how much money you’ll make, and way too little time actually making the thing.
Idea debt指你花了太多時間想象某個項目進行的樣子，想象著這個項目完成以后會有多么了不起，你自己會顯得多牛，會被如何追捧，會賺多少錢，卻根本沒有花時間真正去實施這個項目。我們可以稱之為“空想時期”。

The person who has many ideas with tons of lore and planning, but with little to no execution of those ideas into a tangible product is called an idea debtor.
有很多計劃和想法，卻沒有把任何想法付諸實踐做出產(chǎn)品的人被稱為idea debtor（空想家）。
