What I can't completely understand is most other people's fascination with what the famous among us do with their lips and the rest of their bodies. Why do ordinary people become the target of this curiosity simply by virtue of the fact that other people recognise their names and faces but know almost nothing else about them?

If scientists can't communicate with the public, with policy makers, with one another, the future is going to be held back. We're not going to have the future that we could have.

For me, I find that even though I've accomplished a few things in my life, looking back on accomplishments doesn't give me a sense of satisfaction.

Laugh at yourself, but don't ever aim your doubt at yourself. Be bold. When you embark for strange places, don't leave any of yourself safely on shore. Have the nerve to go into unexplored territory.
