It's always good to be underestimated.

Chocolate is the first luxury. It has so many things wrapped up in it: Deliciusness in the moment, childhood memories, and that grin-inducing feeling of getting a reward for being good.

Men of ill judgment ignore the good that lies within their hands, till they have lost it.

It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years.

If it's a good movie, the sound could go off and the audience would still have a perfectly clear idea of what was going on.
