Christie Brinkley

A smile is like an instant facelift and an instant mood lift.

Smile. It instantly lifts the face, and it just lights up the room.

Share your smile with the world. It's a symbol of friendship and peace.

We need to protect our wilderness areas and national parks. Everywhere you travel, you see blight, denuded mountains, logging. If people know what's going on, they'll become activists to safeguard those places.

When you feel great, you emanate a certain energy that translates as beautiful. I don't care if you have the standard beauty or not; it's that X-factor that comes through, and the basis of that is good health.

At Thanksgiving, I always start at the top of my list and say I'm grateful for friends, family, and good health. Then I get more superficial... like being thankful for my Louboutins.

I love musicians. I think artists are the most amazing people because they're constantly creating beauty for the world. With all the crazy stuff going on in the world, then there's artists reminding us of our humanity and reminding us of our heart and soul and what really matters.

I've always believed in a rainbow diet. As many colors and foods as you can eat, the better, because if you focus on one food, there's bound to be a report that comes out that says, 'Broccoli actually... ' So I mix it up a lot. And I take vitamins, like Biosil, which I take for my hair, skin, and nails.

I like coffee in the morning and decaf green tea throughout the day... When I was younger and modeling, to kick-start a diet I would do a juice cleanse.

Every morning, I make myself a cappuccino with a drawing in the foam. I post them to Instagram with the hashtag #christiecappuccino.

My smile has been my ticket to the world. Smiling releases the same feel-good hormones you get jogging. Caring for your lips and gums is important. I brush my teeth morning and night, alternating toothpaste brands. In addition to flossing, I use a Water Pik to massage my gums and remove food particles.

I really believe that being flexible and grateful contributes a lot to your happiness, which contributes to your health and contributes to your look.

No matter what your age is, you only have now. So it's always about living in the moment and being in the moment... I refuse to let those numbers define me, and I just try to face each day positively.

My age has so little to do with my image of myself because at a certain point, the number just didn't fit how I felt. It has become irrelevant to me. I just don't feel like that number is representative of my spirit, of my energy or my anything!

I really believe in the old expression that what doesn't kill you makes you stronger. It's through adversity that you find the strength you never knew you had.

My mom was always my biggest teacher, my inspiration, my role model. My mom was just the most amazing person. She was like a bon vivant in that she just lived each day to the fullest. As soon as I became a vegetarian, she became a vegetarian.

Some people think happiness is a luxury, but it's a necessity. You need to make space for it in your life.

When doing sports... on the water, it's crucial to stop aging by protecting your skin.
