I was a wayward child, very passionate and very determined. If I made up my mind to do something, there was no stopping me.

I was on the tube just before Christmas. and this girl turned round to me and said, 'Are you Kate Winslet?'. And I said, 'Well, yes. I am actually'. And she said, 'And you're getting the tube?' And I said, 'Yes'. And she said, 'Don't you have a big car that drives you around?' And I said, 'No'. And she was absolutely stunned that I wasn't being driven round in some flash car all the time. It was ludicrous.

I had to grow the hair down there. But because of years of waxing, as all of us girls know, it doesn't come back quite the way it used to. They even made me a merkin - a wig - because they were so concerned that I might not be able to grow enough.

Also for me, I don't make endless movies back to back all the time, I really sort of come to understand and love the characters that I play. And with April and Hanna you sort of go through a weird period of feeling sad about letting them go. Sometimes that takes me a week and sometimes it takes me a couple of months, just so that I can feel I can realign my own thoughts again. I do feel really, really blessed that I've had these opportunities.

I have no regrets. If you regret things, you're sort of stepping backwards. I'm a believer in going forwards.

As a young girl, I never felt attractive. I was fat and unhappy at times, and that kind of thinking stays with you your entire life. There's always going to be a part of me that worries about not looking as slim as other actresses. But at a certain point, when you achieve a lot of your goals and you can be proud of your work, you start to relax more about who you are. And that includes your appearance and self-image - I don't think I look too bad for a mother of two. But women shouldn't have to feel the pressure to compare themselves to actresses or models.

Just coming to terms with the fact that I got to play April Wheeler [Revolutionary Road] and Hanna Schmitz [The Reader] in one year, let alone in my lifetime. I'm very, very aware of how rare that is as an opportunity for any one person. I can't tell you how much I've been able to take away from these experiences creatively. I really, really learned so much about acting, about myself... all of those things. It's difficult to talk about the actor's process without sounding like an arrogant asshole but they really were very challenging.
