Account for every quarter-hour of your day. That’s the promise of the Executive Timebox Grid. It starts with the three highest-impact tasks — the non-negotiables — then maps the rest of your day into 15-minute increments from 5 AM to 9 PM. Timeboxing means the task gets that block and no more, which forces sharper prioritization than calendar blocking ever will.

There’s a delegation column so you track what you’ve passed to someone else and when to follow up. A dot grid section for mindmapping, system diagrams, or whatever surfaces during the day. And an End-of-Day review that closes the loop — measuring completion against intent. Not just what you did, but whether you spent time on what actually mattered.
