It is easy to help children, but it is most difficult to help the grown-up. One may change snow into water and water into ice, but to try to change a character is the most difficult thing one can ever imagine. Therefore it is usually vain to try. But what one can do is to build one's own character; that is in one's own hands. Only, what people are most occupied with is the character of someone else; they are always thinking of the other but they never want to change themselves.
