Jacob Grimm and Wilhelm Grimm

“ I meddle with nothing but what no one else can get or care anything about, and where no one can find you out." So the young man agreed to follow his trade, and he soon showed himself so clever that nothing could escape him that he had once set his mind upon.
The second brother also met a man, who, when he found out what he was setting out upon, asked him what trade he meant to learn. "I do not know yet," said he. "Then come with me, and be a star-gazer. It is a noble trade, for nothing can be hidden from you when you understand the stars." ”

“ Then the eldest said, "Here we must part; but this day four years we will come back to this spot; and in the mean time each must try what he can do for himself." So each brother went his way; and as the oldest was hastening on, a man met him, and asked him where he was going and what he wanted. "I am going to try my luck in the world, and should like to begin by learning some trade," answered he. "Then," said the man, "go with me, and I will teach you how to become the cunningest thief that ever was." ”

“ THE FOUR CLEVER BROTHERS.
"DEAR children," said a poor man to his four sons, "I have nothing to give you; you must go out into the world and try your luck. Begin by learning some trade, and see how you can get on." ”
