To say that something is "worth it" in English, you can say that it is "worthwhile" or "worth the effort/time/money/etc." For example:

This project may be challenging, but it is definitely worthwhile.

I think it's worth the time and money to invest in a good education.

The word "worth" comes from Old English and originally meant "to be worth in value or worth to be bought or sold." Over time, this meaning evolved to include the idea of being valuable or beneficial in a broader sense, not just in terms of monetary value.

Here are some more examples of how "worth" can be used in English:

This book is worth reading. (It will be valuable or beneficial to read this book.)

She's a person worth knowing. (She is valuable or beneficial to know.)

The trip was worth it. (The trip was valuable or beneficial in some way.)

In Chinese, you can say that something is "值得" (zhí de) to mean that it is "worth it" or "worthwhile." For example:

这个项目可能有些挑战，但它绝对值得。 (Zhège xiàngmù kěnéng yǒu xiē tiǎozhàn, dàn tā juéduì zhí de.) (This project may be challenging, but it is definitely worth it.)

我认为投资于好的教育是值得的。 (Wǒ rènwéi tóuzī yú hǎo de jiàoyù shì zhí de de.) (I think it's worth investing in a good education.)
