In fact, because I am very time conscious and want to make the most of every moment, I make it a practice to remove my watch before I light the candles as if to suggest that for this brief period, my life must transcend time.

For me, study is a divine and daily imperative, and I study a page of Talmud daily so that I am not only teaching. My teaching is constantly being fed by my learning.

If people are not safe, they will not make themselves vulnerable. If they feel too comfortable, they can become complacent or lose their curiosity. They can become intellectually lazy about what matters most.

I have a principle I often invoke in class: comfortable people don't grow. Good teachers need to engage in the paradox of making students feel comfortable and uncomfortable in equal measure.

I took to religion at about age 12; it was very hard for me to be Sabbath observant as a kid in a home which was not Sabbath observant. I think my parents thought the whole Jewish thing was a phase.

I don't read or write SF for cutting edge ideas; I read and write it for the storytelling, and every story is new. So have I brought anything new to it? Only in so far as no-one before has written about the characters I've invented in their particular situation.

I would advise anyone who is at the start of a rest ritual like the Sabbath, to take it slowly and grow incrementally into it. Recognize that it will be hard at first. It's a discipline but then it is a true and deep joy.
