To explain what a 'proper use' is, Jesus actually told another story. It's quite an amusing one. It tells of a manager of a company who is dismissed by the owner of the company for wasting resources.

So he writes around to all the people who owe money to the company and tells them that he will settle their bills for half what they owe. When the owner discovered what he had done, Jesus says he had the good humour to congratulate the manager—not of course for his dishonesty, but for his shrewdness. Jesus draws this lesson:
