得不偿失

面对复杂多变的外部环境，我们做事必须做到得不偿失。

miàn duì fù zá duō biàn de wài bù huán jìng, wǒ men zuò shì bì xū zuò dào dé bù cháng shī.

Faced with a complex and ever-changing external environment, we must strive for greater losses than gains.

为了眼前的微小利益而牺牲长远的身体健康，实在是得不偿失。

wèi le yǎn qián de wēi xiǎo lì yì ér xī shēng cháng yuǎn de shēn tǐ jiàn kāng, shí zài shì dé bù cháng shī.

Sacrificing long-term health for small immediate gains is really not worth the gain.
