Brad Pitt is amazed when he looks back on the past 18 months of his life because there has been so many dramatic changes. Pitt split from ex-wife Jennifer Aniston in January 2005 and began dating his Angelina Jolie. By December, Pitt announced he was applying to be the adoptive father of Jolie's already adopted children Maddox and Zahara Marley.

And in May this year, Jolie gave birth to the couple's first biological child Shiloh Nouvel in Namibia.

Pitt says, "The change has been immense. I've become a father, turned 40, and I've become more clear on the direction that I'd like to take and the things that speak to me. In my younger days I was more of drifter. I'd try many things - I'd try anything. But now there's a real pride in understanding myself and what's important to me and my values.

"I still value the work I do, but at the same time I value more getting home to the kids. Maybe it was turning 40 as well. There were certain things I wanted to attack and it seems to work. I go back to the kids and it just makes me more efficient and I get the things done, whereas before I probably meandered and drifted more."
