Difference Principle

Difference Principle does not tell you what to do. It tells you what not to forget while you do it.

Applied daily, it changes less than you hope and more than you expect. That is how principles work — unglamorous, cumulative, and visible only in photographs taken years apart.

What this concept offers is a pause — one extra beat between what happens and what you do about it. Civilisation, someone said, is measured in that beat.

Watch two shopkeepers in the same lane during a lean month. One cuts quality, the other cuts margin. In a year, one has customers and the other has stock.

Money is a good clerk and a terrible master; the arrangement is entirely up to us. You will meet this idea again this week, wearing different clothes. Now you will recognise it.
