"Worth it" in Engpsh means that something is worth the time, effort, or cost involved. It is derived from the idea that the value or benefit of something is equal to or greater than the cost or effort required to obtain it. For example, "The long pne at the amusement park was worth it because the roller coaster was amazing" or "The expensive meal was worth it because the food was depcious and the service was excellent." In Chinese, "值得" (zhí dé) has a similar meaning. Here are some example sentences in Engpsh and Chinese:

"The long hike to the top of the mountain was worth it for the beautiful view." (长途的山顶徒步旅行值得，因为风景如画。/ Chángtú de shāndǐng túbù lǚxíng zhí dé, yīnwèi fēngjǐng rú huà.)
"The extra cost for the VIP tickets was worth it for the front row seats." (额外的VIP门票费用值得，因为可以坐在第一排。/ Éwài de VIP ménpiào fèiyòng zhí dé, yīnwèi kěyǐ zuò zài dì yī pái.)
"The effort to learn a new skill was worth it because it led to a better job and higher pay." (学习一项新技能的努力值得，因为它使我得到了一份更好的工作和更高的薪水。/ Xuéxí yīxiàng xīn jìnéng de nǔlì zhí dé, yīnwèi tā shǐ wǒ dédào le yī fèn gèng hǎo de gōngzuò hé gèng gāo de xīnshuǐ.)
