My aim is to understand love. I know how alive I felt when I was in love, and I know that everything I have now, however interesting it might seem, doesn't really excited me. But love is a terrible thing: I've seen my girlfriends suffer and I don't want the same thing to happen to me. ... Although my aim is to understand love, and although I suffer to think of people to whom I gave my heart, I see that those who touched my heart failed to arouse my body, and that those who aroused my body failed to touch my heart. - Paulo Coelho
