Don't feel badly when you take off work to go for a run, to go for a walk; don't feel badly to take time to play with your children, to be part of their lives. Work is important, but you can't work at your best unless you're a whole person.

Politics is an ugly and thankless role.

I had to divorce my husband, the prime minister. I found it terribly overwhelming.

I tried during the 1974 campaign to show my husband not as the aloof intellectual people think he is, but the warm, passionate man I know. But the day after the election - after I'd worked so hard - I was put back on the shelf. I was devastated.

I just want to find my individuality.

I didn't even like Mick Jagger.

I tend to keep the press at a distance, you know, and I don't really react to what they say. I react to what I feel more.

I don't paint, and I can't draw, but I see things, I think, quite well, and I love being able to freeze things with the camera, particularly the children. Then I discovered with the camera that you can tell a whole story with just freezing a moment in reality. I find it a very good way, a very satisfying feeling.

The secret is to nip any mental disorder in the bud. As soon as you're not feeling yourself, reach out and get some help because you can quickly get better. If you get stuck in it, it's so hard to get out.

I tried to be a good wife, but I was lost in my gilded cage.

Growing up in Vancouver in the 1950s, I was often capricious and temperamental, quick to laugh, even quicker to feel despair, prone to flailing my arms, pouting and crying when things didn't go my way, or I thought something was unfair, or I was bullied by my sisters.

I remember, after my first postpartum depression, I didn't know what had happened to me. I was stuck in this gray depression where I just wanted to retreat and pull the covers over my head and weep. My mother and I, we went to a psychiatrist, and he just patted me on the head and told me I had baby blues, which was not helpful, obviously.

Bad choices make good stories.

You can't fix yourself out of a mental health issue. You can't wake up and say, 'Today I'm not being depressed!' It's a process to get well, but there is recovery.

If you rely completely on protocol, you can become a robot.

We can choose to wake up and grumble all day and be bitter and angry and judge others and find satisfaction in others doing bad instead of good. Or we can we wake up with optimism and love and say, 'Just what is this beautiful day going to bring me?'

Government leaders, researchers, physicians, the pharmaceutical industry, cancer advocates, and many other stakeholders all have a key role in promoting a safer, healthier environment, better nutrition, increased physical activity, and a new emphasis on prevention in cancer research.

Prevention of cancer should be a national goal.

The system designed to study, diagnose and treat cancer in the United States is broken, and it is in urgent need of reform.

More than 40 years after the war on cancer was declared by President Richard Nixon in 1971, we are not much closer to preventing the disease. The National Cancer Institute has spent some $90 billion on research and treatment during that time. When have Americans ever waged such a long, drawn-out and costly war, with no end in sight?

We would like to think that when we take a shower, shampoo our hair, or apply makeup, we are doing so without inflicting harm to ourselves. Being clean and pretty should not oblige us to increase our risk of cancer.

It's challenging to conduct studies of carcinogenic chemicals on humans, because it would be unethical to knowingly expose humans to high levels of potential toxins.

We should demand the enactment of the Prevention and Public Health Trust Fund, and commit as a nation to the prevention of diseases. America cannot afford to do less.

Mammography will remain a controversial issue because it is an imperfect tool involving ionizing radiation. Let's move beyond this method that is decades old and move forward with an early detection method for breast cancer that will not increase a women's cancer risk at all.
