Concentration Grid

What this is

A grid of numbers, 00 to 99, mixed up. Tap them in order, fast as you can. The clock starts on your first tap and stops on your last.

It's a mindfulness tool. Every number is a rep at staying present. Your mind drifts, you feel it. You push too fast, you feel it. The grid shows you your focus in real time.

The research

The grid goes back to Harris & Harris (1984). Straight up: the research doesn't show it makes you "more focused." That's not the point. It's not a hack. It's a way to practice presence and track it over time.
