When you're choosing furniture for your home that's supposed to express who you are, what you are also saying is you want other people to infer what you want them to infer. What if they see something different? Wouldn't it be really depressing if you're trying to be bohemian and instead they see you as Rush Limbaugh?

Being a Sikh meant having to do what Mom and Dad said, and going to temple, and Mom and Dad choosing who I would marry. But going to an American school taught me that I was the one who's supposed to make those choices.

When I was very young, my background as a Sikh-American made me aware of the tensions that underlie choice.

Knowledge should be a public good, and I want my ideas to have as much exposure as possible.

At my school, when kids went into the army at 16, they didn't do it in a gung-ho, Tom Cruise, 'Born on the Fourth of July' way. They were generally - and I hope this doesn't offend them - the more vulnerable members of the class. They enlisted seeking family, and they didn't always find it.

When it came to healthy eating, my parents did their best to set me on the right path. At school, my friends ate McDonalds at lunchtime, but I had a packed lunch that my mother made for me. I hated it at the time, but looking back, I'm glad.

Getting a family into work, supporting strong relationships, getting parents off drugs and out of debt - all this can do more for a child's well-being than any amount of money in out-of-work benefits.

If my subject is alive and is willing to talk to me, I will do it. But I always try to find people who were close, like lovers and family members and work colleagues - because we are what we think we are, but we're also the perception that others have of us. The truth is a sphere. There's always a hidden face.
