Math is like water. It has a lot of difficult theories, of course, but its basic logic is very simple. Just as water flows from high to low over the shortest possible distance, figures can only flow in one direction. You just have to keep your eye on them for the route to reveal itself. That’s all it takes. You don’t have to do a thing. Just concentrate your attention and keep your eyes open, and the figures make everything clear to you. In this whole, wide world, the only thing that treats me so kindly is math.

A person's last moments are an important thing. You can't choose how you're born but you can choose how you die.

Okay, let’s put it this way. I would like to sleep with you. But it’s alright if I don’t sleep with you. What I’m saying is I’d like to be as fair as possible. I don’t want to force anything on anybody, any more than I’d want anything forced on me. It’s enough that I feel your presence or see your commas swirling around me.

There weren't any curtains in the windows, and the books that didn't fit into the bookshelf lay piled on the floor like a bunch of intellectual refugees.

A life without pain: it was the very thing I had dreamed of for years, but now that I had it, I couldn’t find a place for myself within it. A clear gap separated me from it, and this caused me great confusion. I felt as if I were not anchored to this world - this world that I had hated so passionately until then; this world that I had continued to revile for its unfairness and injustice; this world where at least I knew who I was. Now the world ceased to be the world, and I had ceased to be me.

This is what it means to live on. When granted hope, a person uses it as fuel, as a guidepost to life. It is impossible to live without hope.

In his own way, he's lived life with all the intensity he could muster.
