While preparing for the Robert Caro interview, the speaker reread the biographies and recorded their lessons about how to accumulate and use power.

“I've even sent him handwritten letters. I finally got to sit down with him, and I'm very happy with how it turned out. It'll be out tomorrow. In the meantime, as I was preparing for this interview and I was rereading all of these biographies, I was writing down all the lessons that they laid out about how to accumulate and use power, and this video essay is the result.”
