Quote

The Nobel Prize has been a disturbance at the beginning of October for some years. It would be gratifying to win, but it would be quite an ordeal, too, with all the events which go on for two days. I'd think carefully about what I was doing the day it is announced and maybe not be around, or be around, but elsewhere.

Once in a while, I have to pinch myself to remind myself I am Nobel laureate, but that is not part of my work plan every day.

I choose to feel optimistic, because I don't think I could get out of bed if I didn't.

I'm very hopeful. I am very optimistic about the future.

I think it's dangerous to be optimistic. Things could go terribly wrong virtually overnight.

I think that I am a deeply optimistic person.

I am very excited about the future.

I'm optimistic about the future.

I always try to be optimistic, but not to the point where I'm getting on people's nerves.

I'm one of the most optimistic persons in the world. I always believed that - there's another shot, another chance. In boxing, I never gave up. I kept trying, kept trying. Even when things seemed so dim, I continued to push forward to make something happen in my favor.
