"Fear holds us and binds us and keeps us from growing, Nicholas.' Pug's voice took on an insistent quality. 'It kills a small piece of us each day. It holds us to what we know and keeps us from what's possible, and it is our worst enemy. Fear doesn't announce itself; it's disguised, and it's subtle. It's choosing the safe course; most of us feel we have "rational" reasons to avoid taking risks.' He smiled reassuringly. 'The brave man is not the one without fear but the one who does what he must despite being afraid. To succeed, you must be willing to risk total failure; you must learn this."
