In fact, it teaches you to Be Prepared to make a successful career for yourself if you stick to it.
The knights in the old days were ordered by their code of rules to be thrifty, that is, to save money as much as possible in order to keep themselves and not to be a burden to others, and that they might have more to give away in charity.
If they were poor, they were not to beg for money, but had to make it by their own work.
Thus, Thrift is part of manliness because it means hard work and self-denial, and boys are never too young to work for pay, which they should put in the Post Office Savings Bank or some other Government security.
CLEANLINESS
Law 10. A SCOUT IS CLEAN IN THOUGHT, WORD AND DEED.
Decent Scouts look down upon silly youths who talk dirt, and they do not let themselves give way to temptation, either to talk it or to do anything dirty. A Scout is pure, and clean-minded, and manly.
When boys are getting big, they generally want to show off and to impress other boys with their "manliness"—or at least what they think is manliness.
It generally begins with smoking. They think it fine to smoke, so they suck and puff at cigarettes, partly because these are cheap, and partly because a pipe would make them sick.
The reason why half of them do it is because they are arrant cowards, and are afraid of being laughed at by the other boys if they don't do it. They think themselves tremendous heroes, while in reality they are little asses. Then they like to use swear words because they think this makes them appear tremendously ferocious and big. Also they think it the height of manliness to tell smutty stories and to talk dirt.
