What this actually means
The number that surprises people
5.0 hours a day is 1,825 hours a year — 76.0 entire days, awake and asleep, gone into on your phone. Over a decade: 2.1 years of your life.
What those hours could buy instead
Every year, the same time is worth: 228.1 × books read, 2.6 × a language taken to conversational fluency, 6.1 × a marathon trained for, from the couch, 3.7 × a junior-developer level of coding skill. Priced at $25/hour of freelance work, it is $45,625.
Cutting it in half is the realistic move
Going to zero rarely sticks. Halving it to 2.5 hours frees 913 hours a year — enough for 114 books — while keeping the parts you actually enjoy.
What if you changed the number?
Same habit, different size. Each one is a full simulation of its own.
