Isaacson replies, "I think that he kind of felt that if you ignore something, if you don't want something to exist, you can have magical thinking...we talked about this a lot," he tells Kroft. "He wanted to talk about it, how he regretted it....I think he felt he should have been operated on sooner."
I'm looking forward to read the book, although it's hard to tell which are the exact words straight from Steve Jobs, and which are the author's interpretation of what the man thinks.
It's hard not to think about the road not taken. However much we all wish that Steve Jobs had done the surgery earlier and perhaps would've had a better chance of survival, we can't know about what would've happened in this scenario. What if he had complications and that actually would have endangered or ended his life earlier? We just don't know.
