I work all the time; whatever I do, I do it, and I don't necessarily look at it as work. You could say the Auschwitz project was work, or the Lowy Institute is work, or Westfield is work, or the football is work. It is life.
The loss of my father was the most traumatic event in my life - I can't forget the pain.
What is it to enjoy life? Sit at the beach? No. What it is is that you have to do something, you have be productive, make a contribution to the society, to the family, to yourself.
Life has its ups and downs, but you can only look forward.
