Hopkins outlines an advertising approach based on testing and measuring. In this way losses from unsuccessful ads are kept to a safe level, while gains from profitable ads are multiplied. Or, as Hopkins wrote, the advertiser is "playing on the safe side of a hundred to one shot".

"So empty book with tons of beautiful words"
I listened till the end and got almost nothing useful, for example, the author said:
We need training, we need good tools.
I would ask: what training? what tools? The book is so empty! so vague!
It's like a politician saying: We need to save our country!
But How?
