It is physically impossible for a wall-educated intellectual, or a brave man to make money

the chief object of his thoughts; as physically impossible as it is for him to make his dinner the principal object of them. All healthy people like their dinner, but their dinner is not the main object of their lives. So all healthy-minded people like making money--ought to like it and to enjoy the satisfaction of winning it; but the main object of their lives is not money; it is something better than money.

A good soldier, for instance, mainly wishes to do his fighting well. He is glad of his pay--very properly so, and just complains when you keep him ten months without it; still, his main opinion of life is to win battles, not to be paid for winning them.

So of doctors. They like fees no doubt--ought to like them; yet if they are brave and well educated, the entire object of their lives is not fees. They would rather cure their patient and lose their fees than kill him and get it. And so with all other brave and rightly trained men; their work is first, their fees second, very important always, but still second.

The main idea of this passage is that ______.

A．money matters more than work

B．money is not necessary at all

C．money is as important as work

D．money comes second to work in importance
