Sarah "Fergie" Ferguson has weathered countless ups and downs during her nearly 40 years in the spotlight, and today she says she is at peace with her past.

"Someone asked me, 'If you were an astronaut and you could take all the pressure off you, would you leave behind Fergie and Sarah and the Duchess and your past mistakes and failings?'" the Duchess of York, 61 — who became popularly known as "Fergie" in the 1980s after she married the Queen's second son, Prince Andrew — tells PEOPLE exclusively in this week's cover story.

"And I said, 'What are you talking about? They're all my friends.' I made friends with past mistakes. I made friends with Fergie. She didn't know any better. And then Sarah. That's why we experiment. How is it that we're meant to be knowledgeable when we don't know? My Fergie, my Duchess, my Sarah: They're all good people."

"In researching her, I found out more about my own DNA, and I found that resilience and courage and sense of hope and optimism," says the Duchess, who is mom to Princess Eugenie, 31, and Princess Beatrice, 32, and a new grandmother to Eugenie's 5-month-old son August. "I am a full-blown Celtic redhead, and that comes with a great enthusiasm for life, great spontaneity, and also — you just fight on."
