I knew that it was harder to unite two lives than I had imagined growing up. I knew that relationships could be fragile.

I think it's important how I come across to my students. I want them to see how professional women dress.

I have visited classrooms near military bases to learn more about what schools were doing to support their military kids. I met with teachers overseas to learn about the particular needs they face thousands of miles from America. And I listened to my own granddaughter, who dealt with her father's yearlong deployment to Iraq.

I've always believed you've got to steal the joyful moments when you can.

I guess if you are making more money than your mom and dad, you can set your own boundaries.

At 17, I traveled to Mexico in a lemon yellow Mustang and saved money by bunking down in cheap, cockroach-infested flophouses. In my early 20s, I went on to thumb rides through Europe, readily sleeping in train stations, my backpack as a pillow. Once I even hunkered down for a night on a sidewalk grate - for warmth - in Paris.

The way I look at it, everything is a trade. You acquire some money, so then you've got no financial burdens, but everyone wants your money and so who can you trust? Or you've got no money and you can trust anyone, but then you've got the worry to pay bills. Which is worse?

When the producers of 'Why Poverty?' came to me to do a film about poverty in the United States, I asked if I could do a film about wealth instead. I tend to make films about perpetrators, rather than victims.
