According to the context and meaning of Zhuangzi's "I lost myself" (I lost the narrow self-centered "I think the ego is too fucking important"),
I guess this sentence means: my body lives in this world, living through labor, being driven to old age and not resting until death. We should live well and die well.
The key point to understand this sentence is:
1. Zhuangzi's "I" and "I" have different meanings.
2. Zhuangzi thinks that it is better to forget the Jianghu than to haggle over every ounce. It is extremely important for Zhuangzi to protect his life, or "live", without making unnecessary sacrifices.
3. Understanding Zhuangzi's view of life and death may help us better understand what "a good life" means.
Finally, I suggest the questioner that it is not enough to understand the meaning of a sentence for such a profound text as Zhuangzi. We need to grasp the thought of Zhuangzi's full text as a whole in order to understand the meaning of Zhuangzi.
