Feeling unproductive or burned out by mid-day? The problem might not be your workload, but your focus. The 90-minute focus session, used by CEOs, authors, and creatives, is a powerful time-management method based on how our brain naturally works.

Our minds operate in ultradian rhythms-bursts of energy lasting about 90 minutes. By working deeply for a 90-minute block, then taking a 15–30 minute break, you can tap into peak productivity without fatigue.

Start by choosing one task, switching off distractions, and setting a timer. Use headphones, play a specific playlist, or light a candle to signal "focus time." After the session, rest-walk, stretch, or just breathe.

This simple system helps you avoid multitasking, improve decision-making, and finish deep work faster. Writers like Murakami and entrepreneurs like Elon Musk use similar routines to maximize output with fewer hours.

Try just one 90-minute session tomorrow-you’ll feel sharper, calmer, and more accomplished.
