It is wonderful that American students--to my knowledge more than in other countries--earn their living while going through college. The advantage of this is evident: depending upon himself he becomes mature; he gains respect for the value of money and knows what it means to have none; he becomes acquainted with people, acquires an understanding of their psychology and social relations; he learns what to expect of them if he treats them right and how one can fail if one does not.
