First, you must understand my motivations for writing. The motivation for my autobiography came largely from wanting to challenge, draw out, and enlighten those whom I have loved and despised. The motivation for all subsequent books came from a desire for self-reflection and to create a space in which I could view events in a linear, logical way. That people consume my stories with fervor and pleasure makes me dizzy with satisfaction. At the very center of it all, however, the books are not written for them. They are written for me.
You say some of the details are superfluous, and perhaps they are if I was aiming for literary perfection. But I was not. See, some of the smallest details have the greatest impact on me, and it feels wrong not to include them. How do I properly convey an entire person to you without detailing their life, especially if they have dictated it to me? The hope is that their story moves you the same way that it moved me upon first hearing it. Even though their history might not have any bearing on the overall story, it is incredibly important to me as it is to them. It’s their history after all.
Or perhaps I am simply bad at “saying more with fewer words,” but I like my words too much to reduce them to something less than what they are. It’s an injustice.
