I love the Boy Scout motto: Be Prepared.
The motto traces back to a book published in 1908 titled Scouting for Boys. The author was Baden Powell, who also founded the Boy Scouts Association in England that same year. A short two years later the Boy Scouts of America were established and quickly grew to become the largest youth organization in America.
When Powell was later asked exactly what one should “Be Prepared” for, his answer was ‘Why, for any old thing.‘ He wasn’t kidding.
