I'm not easily inhibited by the fact that I don't know something about a subject. It doesn't stop me from dabbling in it.

I was a bad practicing physician because I was never sure of the diagnosis or of the treatment.

I have many shortcomings. I feel very lucky to have been able to have what I've had.

When I was in high school, I became interested in cytochemistry: chemical analysis under the microscope, and trying to understand the composition of cells.

I hope I've lived a life of science whose style will encourage younger people.

I think we have to believe we are here for some purpose, and I know there are many cynics who will deny it, but they don't live as if they deny it.

Being successful at a very young age gave me the confidence and the capability to try out other things.
