“‘Only as a warrior can one withstand the path of knowledge,’ Don Juan said. ‘A warrior cannot complain or regret anything. His life is an endless challenge, and challenges cannnot possibly be good or bad. Challenges are simply challenges. The basic difference between an ordinary man and a warrior is that a warrior takes everything as a challenge.’ He went on, ‘While an ordinary man takes everything as a blessing or a curse.'” — Carlos Casteneda, Tales of Power
