The beauty of the world has two edges, one of laughter, one of anguish, cutting the heart asunder.

We are all searching for something, but we don't always know what it is.

The world is full of signs and wonders, but we are blind to them.

You can't just keep doing what works one time, everything around you is always changing. To succeed, stay out in front of change.

Science should serve humanity, not the other way around.
