Passage: You must plan to earn a living. You must think carefully about the type of work you would like to do. You should choose a job which will bring you enough money for your needs. More important, it should help you make a contribution to society. In mines, factories, or offices people work with lots of hardship for the money that supports them. No matter where the money comes from, one thing is true: you have to earn it. Each of us must do his share. What is the best title for this passage?
