Social media and the Internet haven't changed our capacity for social interaction any more than the Internet has changed our ability to be in love or our basic propensity to violence, because those are such fundamental human attributes.

It is well to look around at whom, and not just what, surrounds us. Population structure will change everything. Our health, wealth, and peace depend on it.

Happiness is that state of consciousness which proceeds from the achievement of one's values.

When I read out loud in class, it was a joy for everyone else because I would mispronounce things so badly. I used to try to count how many people were in front of me and then work out which paragraph I would have to read out and start trying to learn it. And I would sit there thinking, 'Please let the bell go so that it doesn't get round to me.'
