Jonathan Swift (1667-1745) wrote an excellent essay titled ‘Hints towards an essay on conversation’. For people wanting to improve their conversational skills, it helpfully outlines a set of errors to avoid.
His most important point: “Nothing is more generally exploded than the folly of talking too much.”
In a day and age where anyone can speak, at any time, on any platform, an ability to show restraint and to only say what is necessary will shine through.
