Нужно СРОЧНО перевод:
By the way in which a man uses his leisure his character can be told - more surely, in all probability, than the way he does his work. For most men, work is necessity in order to gain a living. Vast numbers of men have not been able to choose what work they would do, but have been forced by economic necessity to take the first job that came their way. But in their leisure time, they do what they really want to do and their real selves are reflected in their actions.Some people are completely passive during leisure hours. If such people go out they go to some place of entertainment where no effort is required by them, a cinema or a dance-hall, and if the latter, they do not dance but simply sit and watch other dancing.A different type of person hurries home from work full of eagerness to begin on some scheme which he has been planning for his leisure time. Perhaps his hobby is carpentry or model engineering or gardening. This is the creative type of character. For him, his leisure hours are full of promise and he can look back on them with satisfaction when he reviews what he has achieved in them.Millions of people all over the world like to travel during their holidays. They travel to see other countries and continents, modern cities and the ruins of ancient towns, they enjoy picturesque places, or just for a change of scene. It is always interesting to discover new things, different ways of life, to meet different people, to try different food, to listen to different musical rhythms.
