Wolff made the comments in a soon-to-be released book, ‘F1 Racing Confidential’, written by The Guardian’s F1 correspondent, Giles Richards.
The book is a series of 20 interviews with figures from six F1 teams and the championship’s tyre supplier, Pirelli – outlining the nature of their roles and their life histories.
Wolff’s interview ends with him musing about what his future holds at the Mercedes squad where has been a co-owner since 2013, when he also joined as its managing partner and overall head of Mercedes motorsport.
He recently committed to a new three-year contract as Mercedes’ team principal, a title he has held since his former co-executive director, Paddy Lowe, left at the end of 2016.
“Life is full of surprises,” Wolff said. “I would never have imagined I would be here or the success of this team.
“I am 52 now. It sounds like an old age but hopefully there are another 30 years of Mercedes F1 for me.
“It's important that when you hand over the baton at 80, you can say: 'That was pretty good. I am happy with myself - I met my own expectations of my life'.”
Another revealing passage of Wolff’s interview concerns what he told the Mercedes board about its F1 championship expectations in the underwhelming years that followed the Silver Arrows returning in a works team capacity back in 2010.
