Let me introduce a couple of technical terms: extrinsic value and intrinsic value.

外在价值和内在价值。

I originally took this job because it gave me the extrinsic pleasure of money.

起初做这份工作是因为钱所带来的外源性快乐。

And you have to rely on other extrinsic rewards to get you up and going again.

你需要依靠外界其他的奖赏，来驱动你继续前进。

I'd like to make a distinction between 2 kinds of pleasure: extrinsic and intrinsic.

现在，我要区分两种愉快：外源性和内源性。

If I value something as a means to something else, then it has what we will call “extrinsic value.”

如果我视某件事物为达到其他事物的手段，那么这件事物就有“外在价值”。

" Extrinsic" would be something that comes from the outside.

“外在” 是来自外部的东西。

Extrinsic motivation, things like rewards and punishment, does have its uses too.

外在动机，如奖励和惩罚，也有其用途。

" Intrinsic" can sometimes also be used to compare or contrast with " extrinsic."

“内在” 有时也可以用来与“外在” 进行比较或对比。

We have to explain them by appeal to an extrinsic cause.

我们必须用一种外在原因加以解释。

Whether it is intrinsic or extrinsic, motivation influences one's willingness and enthusiasm to learn.

無論是內在還是外在, 動機都會影響一個人的學習意願和熱情。
