The quote from Mark Twain that has a serious tone is:
“Courage is resistance to fear, mastery of fear, not absence of fear."

The first two lines in this excerpt from "A Grain of Sand" by Frances Ellen Watkins indicate its subject, which is the very grain of sand. In the first line it is mentioned explicitly, whereas in the second one it is replaced with the third person singular pronoun <em>it</em>: "Do you know to me it (the grain of sand) brought just a simple loving thought?". It is a quite common resource for authors, since the use of pronouns prevent poems, as well as other kinds of literary and non-literary works, from being repetitive, that is, pronouns help authors avoid using the same word or term over and over again.
