     How often one hears children wishing they were grown-ups and old people wishing they were young

again! Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each

age gives him without wasting his time in useless regrets.

     Childhood is a time when there are few responsibilities to make life difficult. If a child has good

parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in

his life be given so much without having to do anything in return. In addition, life is always presenting new

things to the child - things that have lost their interest for older people because they are too well-known.

But a child has his parents. He is not so free to do what he wishes to do; he is continually being told not

to do things or being punished for what he has done wrong.

     When the young man starts to earn his own living, he can no longer expect others to pay for his food,

his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time

playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society

as he used to break the laws of his parents, he may go to prison. If, however, he works hard, keeps out

of trouble and has good health, he can have the great happiness of building up for himself his own position

in society.
