Einstein and Tesla were known for talking to themselves, using external self‑instruction to engage both speech and hearing channels, which doubled processing and helped them develop theories. Experiments with shelves showed that speaking a word aloud speeds up retrieval by activating visual memory. Children naturally use self‑talk for learning, a habit adults suppress. There are three useful types of self‑talk: instruction, motivation, and analysis, all of which Einstein employed daily. His secretary later recalled how he would walk around debating with himself, asking questions and answering in different voices, a process that seemed insane to outsiders but birthed revolutionary physics. The video encourages viewers not to fear self‑talk, as it can sharpen thinking.
