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.

In every life there is a challenge. For every challenge that I take on, if I follow through, I accomplish. When I have accomplished, then I have achieved. If I achieve, than I can proudly say I did my job well.

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.

For some reason, I write about crash-landed spaceships quite a lot and my wife is sick of hearing of hearing my ideas for new tales about them.

Teaching is almost like an act of prayer for me. I feel that I am present at the intersection of people and ideas in a very holy way. There are not many places where successful adults can take a break from work or domestic issues and freely and safely explore their inner lives or global issues through an ethical lens.

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.
