Like many of us, I talk to myself out loud, though I’m a little unusual in that I often do it in public spaces. Whenever I want to figure out an issue, develop an idea or memorise a text, I turn to this odd work routine. While it’s definitely earned me a reputation in my neighbourhood, it’s also improved my thinking and speaking skills immensely. Speaking out loud is not only a medium of communication, but a technology of thinking: it encourages the formation and processing of thoughts.
