Arianna Huffington And Sheryl Sandberg On The Power Of Optimism

Joining Arianna Huffington at the World Economic Forum in Davos, Facebook COO Sheryl Sandberg discussed why she thinks a sense of optimism is central to reaching the solutions the world needs.

"There's so many real challenges in the world," said Sandberg. "Jobs challenges, connectivity challenges, challenges for democracy. And I think optimism matters, because unless we're optimistic, we give up. The challenges are real -- there are real challenges all over the world -- but the opportunities have never been better."

Extend Good Manners

I grew up on the rules of Emily Post in a family where niceties -- like holding the door open for someone -- were more expected than a pleasant surprise.

Good manners have multiple, positive benefits. I try to practice them on a regular basis -- even if it's just saying "please" and "thank you."
Speak Words Of Kindness

I strive to tell others when they've made a difference in my life on a daily basis. If I'm being completely honest, accepting myself also means knowing I wouldn't be who I am without the amazing people around me.

A genuine compliment can go a long way. Did someone inspire you today? Were they a great friend during a time you needed it most? Tell them. They'll appreciate it more than you know.
Practice Forgiveness

I try to make forgiveness a habit, mostly because the alternative of holding onto a grudge can be exhausting. Everyone makes mistakes.

Research shows holding onto anger can harm your well-being; it's much healthier to let it go. Practicing forgiveness can lead to less stress and anxiety, boost your heart health and help your self-esteem, according to the Mayo Clinic.
Express Gratitude

The health perks of gratitude are hard to ignore. Thankfulness can make you more optimistic, help you feel less lonely and even lower your blood pressure.

I try to make expressing gratitude a daily exercise, whether it's reflecting on the positives of my day as I go to sleep or writing them down in a journal. Think of it as a workout for your brain.
