the only chapter of your life you'll never remember writing.
means The earliest stage of a life or a thing's existence, when it is brand new and not yet developed.
from From Latin infans, literally "not speaking" — from in- ("not") plus fans, the present participle of fari, "to speak." A Roman infant was, quite precisely, the one who could not yet talk. The word reached English through Old French enfant, and over time stretched beyond babies to cover anything in its speechless, just-begun phase — a science in its infancy, a nation in its infancy, all of them too young to explain themselves.
