Don Quixote by Spanish author Miguel de Cervantes
"I've come to believe that there exists in the universe something I call 'The Physics of The Quest' -- a force of nature governed by laws as real as the laws of gravity or momentum. And the rule of Quest Physics maybe goes like this: 'If you are brave enough to leave behind everthing familiar and comforting (which can be anything from your house to your bitter old resentments) and set out on a truth-seeking journey (either externally or internally), and if you are truly willing to regard everything that happens to you on that journey as a clue, and if you accept everyone you meet along the way as a teacher, and if you are prepared - most of all - to face (and forgive) some very difficult realities about your self... then truth will not be withheld from you.' Or so I've come to believe. I can't help but believe it, given my experience."
