Most people can label what they did with an hour. Far fewer can say whether it was worth having. That second judgment — lived or lost — is the whole point, and a few concrete examples make it much easier than any rule.
When you grade an hour, you write one honest sentence and give it a color. Green means lived — an hour you'd choose again. Amber means neutral — necessary but forgettable. Red means lost — wasted or unaccounted for.
The trap is assuming "lived" means "productive." It doesn't. Rest, people and honest play all count as lived. A slow dinner with someone you love is green. A frantic hour of busywork you'll forget by Friday might be amber, or even red. The line is intention, not output — the same line at the heart of how to grade your hours.
The most useful thing to understand is that the activity alone doesn't decide the color. The same hour can be lived or lost depending on how you actually spent it.
Read down the "deep work" and "TV" rows in particular. The task is identical; the verdict flips entirely. That is the point of writing the sentence first — it forces you to notice what the hour actually was before you color it.
Some hours are easy. If you'd live them again without hesitation, they're green:
- Focused work you chose — the task that needed your best attention, done with your best attention.
- Real rest — a walk, a nap you needed, sitting with a coffee and no agenda. Rest is not the opposite of lived; done honestly, it's a form of it. If rest is the part you struggle to score, see how to grade sleep, rest, and downtime without guilt.
- People — an unhurried conversation, a meal together, time with someone you'd miss.
- Honest play — a hobby, a game, a film you genuinely wanted, fully present.
None of these have to be useful. They have to be chosen. If you're unsure where the boundary sits, what counts as lived time walks through the edge cases in more detail.
Red is not "unproductive." Plenty of unproductive hours are richly lived. Red is for time that was genuinely wasted or that vanished:
- The scroll that left you flatter than before you started.
- The show you half-watched while doing nothing else, and can't recall.
- The argument you kept relitigating in your head instead of letting go.
- The hour you honestly cannot reconstruct at all.
That last one deserves its own note. When you can't account for an hour, mark it red and move on. Unaccounted time is the clearest signal that the day ran you rather than the reverse — and it only counts if you're honest about it.
Most days are mostly amber, and that is fine. Amber is the necessary, forgettable machinery of a life: admin, chores, the commute, the meeting that had to happen. You wouldn't choose these hours for their own sake, but you don't resent them either. They kept the lights on.
The mistake is trying to turn every amber hour green. A life of all green would be exhausting and probably dishonest. The goal isn't to eliminate amber — it's to make sure amber isn't quietly eating the hours that should have been green, and that red isn't hiding inside it.
When amber tips into red
Watch for amber activities doing red work. "Checking email" is amber; refreshing your inbox for the tenth time to avoid a hard task is red. A ten-minute break is amber; the break that swallowed ninety minutes is red. The sentence you write usually gives it away.
One graded hour tells you nothing. A month of them tells you everything. As the days fill in on the month color grid, the pattern stops being something you believe about yourself and becomes something you can see — where your green hours cluster, where the red quietly repeats at the same time each day.
Then you change one thing, not everything. Protect the window where green tends to happen. Cut the one recurring red drain. That is more useful than any resolution to "waste less time."
And if you want the reason the coloring matters at all — why a single lost hour is worth noticing — it's the oldest reason there is. The hours are numbered. Scoring them lived or lost is just the honest accounting of a life you don't get to keep, which is what memento mori asked of you all along.
