As long as you try your best, that is all that matters. You don't have to be the fastest runner or top of the class.
I got the best of Rod. And I am fully aware that, even though I love listening to his stories of the crazy days, no relationship could really last then. I sometimes wish I could go back in time to the 1970s or 1980s, sit at a bar, and observe him, but I'm glad our time came when it did.
I used to be very into fitness and would happily pose for photos in my bikini. Now I look at those and think, 'Where did that body go?' But that was before children.
I was bullied from the age of 11 onwards. I was always much bigger than the other kids. I spoke nicely, didn't swear, and I refused to try to fit in and be like everyone else. People assumed I thought I was above everyone else.
There's certainly never a dull moment in the Stewart clan.
Rod's always been a keen sportsman, so he didn't live as excessive a life as some musicians.
If I had a partner who asked when I was going to the gym or commented that I was eating too much or asked if I really needed an extra potato, that would make me feel awful. It would be terrible.
I modelled in my 20s, and it was an obsessive time. I was under pressure to look a certain way.
I really do believe that being naturally beautiful is what is inside and what shines through.
I think there's always interest in how the other half live - I see myself as a down-to-earth Essex mum who just happens to be living this very glamorous life in Beverly Hills.
The truth is I'm a very traditional woman, and Rod - despite everything people may think - is a very traditional man. It's true he absolutely loves glamour, and he hasn't got a conventional job, but performing aside, he's happiest at home with his kids around him or lounging in front of the fire watching a war documentary like 'D-Day Remembered.'
As parents, it is our responsibility to show by example and educate our children on the importance of caring for our planet.
