What this actually means
The number that surprises people
1.5 hours a day is 375 hours a year — 15.6 entire days, awake and asleep, gone into commuting. Over a decade: 0.4 years of your life.
What those hours could buy instead
Every year, the same time is worth: 46.9 × books read, 0.5 × a language taken to conversational fluency, 1.3 × a marathon trained for, from the couch, 0.8 × a junior-developer level of coding skill. Priced at $25/hour of freelance work, it is $9,375.
Cutting it in half is the realistic move
Going to zero rarely sticks. Halving it to 0.8 hours frees 188 hours a year — enough for 23 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.
