You write down a perfect to-do list in the morning. By 5 PM, you’ve done 45 minutes of real work, scrolled for two hours, and spent the rest of the day answering pointless emails. You feel exhausted, yet nothing got done. Where did the day go? Traditional time trackers let you lie to yourself. You start a timer, get distracted, and leave it running for three hours.
