This week’s idea is flux: the simple but unsettling idea that everything changes. It’s a fitting place to begin the renewed Weekly Wisdom Builder, now a research-and-learn branch of my TST Weekly Column. Rather than racing through topics, each week pauses on a single idea and explores it. Flux felt like the right starting point—not just as a concept, but as a reminder that change itself can be a source of wisdom.
This week’s reflections draw on Heraclitus and the ancient roots of impermanence, touching on everything from the constellations above us to the brief stretch of time each of us occupies here on Earth.
