What this actually means

You are creating a second workday every week

3.0 hours a day is 1,095 hours a year — the equivalent of 27.4 extra 40-hour work weeks, without changing jobs.

What fits in that time

Per year: 136.9 × books read, 1.6 × a language taken to conversational fluency, 3.7 × a marathon trained for, from the couch, 2.2 × a junior-developer level of coding skill. The constraint was never time in the abstract; it was time at a predictable hour.

The catch

Waking earlier only creates time if the extra hours do not come out of sleep. Taken from sleep, the hours are real but their quality is not — see what happens if you sleep 6 hours a night.

What if you changed the number?

Same habit, different size. Each one is a full simulation of its own.
