What is self commentary?

Self commentary, as discussed by David Heinemeier Hansson on the Tim Ferriss Show, involves having a running narrator in your head while learning or performing tasks. This internal dialogue constantly points out areas for improvement and suggests next steps. It acts as a feedback loop that helps in tasks like racing, programming, or any iterative process. By repeatedly evaluating and tweaking one's actions, self commentary aids in faster and more efficient learning 1.
