This week, we discuss the connection between purpose and happiness. Are they connected? Does one precede the other? What happens to our work when we no longer feel any purpose in engaging in it? Does it merely become practice? If so, to what end? Also, a reflection on the life of Gene Cernan and men like him, who dared to leave their home behind “just to see if they could do it.” Luigi Ghirri is our Photographer of the week.
