That to be an activist, you have to stay active. For me, it's profound; it's not something you choose to do every five years because it's chic to say it.

One thing my mother always instilled in me is to always know my worth. Don't settle for less. She used to say to me 'Iman, no is a complete sentence, learn to say no. You don't have to explain it you don't have to say anything after it. It's a complete sentence.' So when I came to America 1975, I found out that the black models were being paid less than white models. So the first thing I did was say I'm not going to do the job unless I'm paid the same amount.

Bethann Hardison has been my collaborator, my closest friend, we've gone through starting businesses, losing businesses, kids, divorces, marriages, and she was my maid of honor when I married my husband, David Bowie. And she's still such a part of my life. This is the person when it's totally dark, outside and inside, this is the person I would call.

I came from a background where I was very poor growing up but I have never known poverty. My parents worked hard and they went to bed hungry, but they fed us. Then my father became an ambassador, so I ended up being driven by chauffeurs. And then we became refugees. After that, I looked at it through this "glass" of to have and have not, and at the end of the day, who actually helps, who actually steps up, who is there for you.

Make sure your decision to have a child is based on the need to share your life completely with another little human being and not because of some personal need for validation as a woman.

We grew up as poor people but we never knew poverty. I still love and miss the Somalia I grew up in. Things changed, when my father became a diplomat later on.

My saving grace was that I always knew when to leave the party.
