Why your brain lies about time.

Time blindness, ADHD tax, and why ‘ten minutes’ is almost never ten minutes.

Time, but make it slippery.

You estimate ten minutes. It takes forty. You feel like a fraud.

Welcome to time blindness — the part of executive function that turns the clock into a guess. It's not laziness. It's not bad planning. It's your prefrontal cortex doing its best with limited bandwidth. Here's the thing: most productivity advice is built for brains that already track time well. They tell you to "block your calendar" or "time-box your tasks." Cool, but you have to *know* how long things take to do that. And you don't. Yet.

That's where measuring beats guessing. The first time you actually time how long replying to email takes, you get a number. The fifth time, you get a baseline. The twentieth time, you get truth — and truth is what unlocks the schedule that doesn't lie back to you. In FocusBlobs, this is the whole point. Make a task. Time it once. Now you have a real number to plan from. No shame, no streaks, no guilt — just a quietly accumulating record of how time actually moves through your day.

The blob isn't here to fix you. The blob is here to keep you company while reality sets in.
