What do you expect to regret, and is there still time to do something about it?

Instead, I am badly oppressed by a gnawing sense of waste. I had real plans for my next decade and felt I’d worked hard enough to earn it. Will I really not live to see my children married? To watch the World Trade Center rise again? To read—if not indeed write—the obituaries of elderly villains like Henry Kissinger and Joseph Ratzinger? But I understand this sort of non-thinking for what it is: sentimentality and self-pity.

And of course, I wonder why I was not more vigilant about checking my skin, because if I had been, I would have picked up that first melanoma before it turned bad, and saved myself a lot of heartache. When I was first diagnosed, I was angry with myself for being too lazy and stupid to bother with anything but the occasional quick examination. But then I decided that kind of thinking was a waste of my time, because we start dying the moment we are born. I know that now. The knowledge has changed from a first illuminating but soon forgotten premonition into an undeniable lived reality.

I was terribly upset at the time, because I felt I had betrayed [my wife] Kate and my family by being so stupid. But I’ve accepted it.
