Each thing you learn makes the next one easier to understand. A little every day builds into a lot, the way money does.
Thirty minutes a day for ten years is about 1,825 hours: as many hours as a full year of working days.
This stage is 48 Red Lines and From Zero is 48 more. One a day, each takes about seven weeks.
Reading more is useless without acting on less.

- A Strong proof: Many good studies or long official data, from different teams or countries, point the same way.
- B Good proof, with limits: Solid studies agree on the direction, but the size varies, or the data covers few places or few kinds of people.
- C Mixed proof: Some good studies for, some against, or the evidence covers only part of the line.
- D Thin proof: Mostly one book’s argument, one survey or stories. It may be wise, but it has not been tested well.
- = True by the sums: It follows from arithmetic, so no study can overturn it. We still show what real data says.
