I've written what and when I want to. It's been about expressing myself. But with the degree, I had to learn to do everything in a very specific, disciplined way. I am very disciplined, but this demanded a totally different kind of discipline. A real challenge.

Some people regard discipline as a chore. For me, it is a kind of order that sets me free to fly.

We should remember that there was once a discipline called natural philosophy. Unfortunately, this discipline seems not to exist today. It has been renamed science, but science of today is in danger of losing much of the natural philosophy aspect.

The poor are prevented from thinking by the discipline of others, the rich by their own.

Age acquires no value save through thought and discipline.
