Angelina Jolie can't relax.

The 42-year-old actress-turned-director - who raises six children, Maddox, 16, Pax, 14, Zahara, 13, Shiloh, 11, and nine-year-old twins Knox and Vivienne, with estranged husband Brad Pitt - finds a ''real pleasure'' in the fact she rarely gets any time to herself and wouldn't change things for the world.

Asked how she relaxes, she said: ''I really don't [relax]. I'm one of those people. It drives me nuts when people tell me to relax.

''I think a lot of moms don't really rest. And somehow we find a real pleasure in that.

''I mean, even if I try to take a bath, I'll end up with at least two of my kids in there with me, which is lovely. I wouldn't trade it at all.''

When it comes to raising her children the 'By the Sea' star believes the most important lesson she can teach them is to value others, as she thinks all the bad things in the world stem from selfishness and a lack of empathy.

Asked what she teaches her children, she told Britain's HELLO! magazine: ''To value others. If you live life and walk around thinking of yourself and your own needs and desires then not only is it a selfish life, but it ends up being quite an unhappy life, I imagine. And that's where everything goes wrong.

''The wars and hostility, the ugliness and inhumanity in this world comes from this lack of being able to have real empathy for someone else.

''If you can value others, I think things naturally balance out in your own life. When you don't live with ignorant perceptions and that smallness, you open up in a beautiful way.''
