L'optimisme, ce n'est pas le refus de voir ce qui ne va pas, c'est le désir de ne pas s'y attarder. // Donne moi le courage de changer les choses que je peux changer, la sérénité d'accepter celles que je ne peux pas changer, et la sagesse de distinguer entre les deux. (Marc Aurèle) // Don't raise your voice; improve your argument. (Desmond Tutu) // Be the change you want to see in the world. (Gandhi)


I found debriefings were almost like confessing my sins to a priest
—except that this was done over a microphone, 
so the whole “congregation” heard my mea culpas, 
particularly when I had to say what all of us learned to say: “I don’t know.” 
Knowing what we didn’t know was how we kept people from getting killed.
(Gene Kranz, in Failure is not an Option: Mission Control From Mercury to Apollo 13 and Beyond)
