Life is thick sown with thorns, and I know no other remedy than to pass quickly through them. The longer we dwell on our misfortunes, the greater is their power to harm us.
 
[La vie est hérissée d’épines, & je ne sçais d’autre remède, que de passer vite à travers ces broussailles. C’est donner de la consistance aux maux, que de trop s’y arrêter.]

Voltaire (1694-1778) French writer [pseud. of Francois-Marie Arouet]
