Passage
The day of the big game, I woke up with a knot in my stomach. Even though I had practiced hard, I was still really nervous. But I got ready and arrived there early. The coach was in the locker room going over the game plan. When I told him how nervous I was, he said that fear is like a stray cat; if you let it in, it will rip up all your furniture — but if you look it straight in the eye, it will turn tail and run.

Explanation:

glamis thou art, and cawdor; and shalt be what thou art promis'd; yet do i fear thy nature; it is too full o' the milk of human kindness to catch the nearest way: thou wouldst be great; art not without ambition; but without the illness should attend it. what thou wouldst highly, that wouldst thou holily; wouldst not play false, and yet wouldst wrongly win: thou'dst have, great glamis, that which cries, "thus thou must do, if thou have it: and that which rather thou dost fear to do than wishest should be undone." hie thee hither, that i may pour my spirits in thine ear; and chastise with the valor of my tongue all that impedes thee from the golden round, which fate and metaphysical aid doth seem to have thee crown'd withal.
