All my conceit comes from my inferiority, and all my heroism comes from my weakness. Where does this sentence come from

This sentence comes from the artist Ma Liang's Confessions, which originally read:

All my conceit comes from my inferiority complex, and all my heroism comes from my weakness. I speak eloquently because my heart is full of doubt, and I am affectionate because I hate my ruthlessness. Nothing in this world is born in vain. Standing in the light, there will be shadows behind you. There is silence in the middle of the night because you haven't heard the sound yet.

The Invisible City by Italian writer italo calvino is similar to this sentence, because:

All my conceit comes from my inferiority, all my heroism comes from my inner weakness, and all my eloquence comes from my heart full of doubts. I pretend to be heartless, but I hate my deep feelings. I thought the meaning of life was wandering around in exile, but it was just a cover-up that I had not found a place to stop.
