This story I remember to have read many years ago.
The couple who founded Reader's Digest had a unique method to work.
When on work, they will not speak with each other. If any of them had any query, they will 'Talk' with each other by writing and by exchanging chits.
Now pause here and try to understand effect of above method.
By keep talking trivia, we often lose lot of concentration.
A rule to not speak when on serious work, has enormous benefits.
