The Marquis De Sade said that the most important experiences a man can have are those that take him to the very limit; 

that is the only way we learn, because it requires all our courage. 

 people who have never dared to look into the depths of their soul, 

never attempted to know the origin of that desire to unleash the wild beast,

 or to understand that sex, pain and love are all extreme experiences. 

Only those who know those frontiers know life; 

everything else is just passing the time,

 repeating the same tasks, 

growing old and dying

 without ever having discovered what we are doing here
