Cognitive scientists call it 'cognitive load' — the invisible tax your working memory pays when too many decisions, tasks, or unresolved questions compete for attention at once. George Miller's famous 1956 research showed that the mind can juggle roughly seven chunks of information before performance degrades. What's less often discussed is what Zen teachers have observed for centuries from the opposite direction: a mind cluttered with pending judgments doesn't just think slowly — it stops seeing clearly altogether. The Japanese term 'mushin' (literally 'no-mind') isn't about emptiness for its own sake. It describes a state where the practitioner has cleared the mental queue enough that response becomes accurate rather than reactive. The practical takeaway isn't meditation — it's triage. Before your next important conversation or decision, spend ninety seconds writing down every unresolved item orbiting your attention. Getting it out of working memory and onto paper doesn't solve those things, but it stops them from silently degrading the thinking you're actually trying to do.

In the last 48 hours, which decision did you make while your attention was clearly split — and what might you have noticed if it hadn't been?
