I went into the sciences very early on, but to me, economics pervades so much more of our lives and our existence.

There's not a single country that actually approaches economics in a pure, free market, capitalist way. I like the free market - but it very much exists only in textbooks. If I had a choice, and we could live in a very pure world, I would be a supporter of the free markets.

There is a time of reckoning in all our lives.

Very few of us can stop our lives and become activists.

Most astronomical work has to do with things that are very, very far away and don't affect our lives very much.

We can change our lives. We can do, have, and be exactly what we wish.
