It is a far, far better thing that I do, than I have ever done; it is a far, far better rest that I go to than I have ever known. — A Tale of Two Cities

My Take – Sydney Carton knew his fate, and went to it with his head high.  Few of us deliberately die for others as he did, but we all do things that are unpleasant or painful for our own good or for the good of others.  The worst moments of my life happened after I looked at myself in the mirror, admitted that what I was about to do would be painful, would last for a very long time, and would stay with me to my grave, but were necessary and I had to get on with it.  Yes, they sucked, and yes I still wince when I think of them, but I’m better off because of them, and I’m glad I went through them.  When those moments come to you, I hope you make the right decision.
