"Passion doesn't count the cost. Pascal said that the heart has its reasons that reason takes no account of. If he meant what I think, he meant that when passion seizes the heart it invents reasons that seem not only plausible but conclusive to prove that the world is well lost for love. It convinces you that honor is well sacrificed and that shame is a cheap price to pay. Passion is destructive. It destroyed Antony and Cleopatra, Tristan and Isolde, Parnell and Kitty O'Shea. And if it doesn't destroy it dies. It may be then that one is faced with the desolation of knowing that one has wasted the years of one's life, that one's brought disgrace upon oneself, endured the frightful pang of jealousy, swallowed every bitter mortification, that one's expended all one's tenderness, poured out all the riches of one's soul on a poor drab, a fool, a peg on which one hung one's dreams, who wasn't worth a stick of chewing gum."
- W. Somerset Maugham
"Regret for the things we did can be tempered by time;
it is regret for the things we did not do that is inconsolable."
- Sydney J. Harris
