Real culture is a matter of personality, not mathematics or history or grammar. All these different studies are practical studies, but the real study is how to develop personality. If you are a business man, a lawyer, a professional man., an industrialist, a politician, whatever be your occupation in life, you are forced, expected, to have a personality in every walk of life. It is the personality of the salesman which sells, not always the goods. In the case of a doctor it is his personality which can heal and cure a person much sooner than medicine can.
