I see some people stay in one place because it's convenient or it's comfortable. But they're missing out on their passion.

A lot of effort and money are - rightly - expended keeping the president physically safe. But it's up to the president to maintain a schedule that allows for refueling, so as to be physically and cognitively at his or her best at all times. That's what it means to be strong, tough, and truly fit for the highest office.

If you want to have the clarity and steadiness to deal with that '3:00 A.M. phone call,' you should better have made sure that you're not running on empty when that phone rings.

Trump's executive order on refugees, his endless petty feuds - with allies, with judges, with Arnold Schwarzenegger - his constant stream of up-is-down and down-is-up fabrications is outrageous.

Any president's actions have real consequences in real people's lives.

If we live in a perpetual state of outrage, Trump wins. Because when we become depleted and exhausted and sapped of our energy, we're not as resourceful, creative, or effective.

When it comes to our collective health, how we deal with the multiple crises and problems around us also depends on the power of context - in other words, our resilience.

Women need to lead the way to change our culture of burnout - both for their sake and also for the sake of successful men who desperately need a new model of success. And the still-very-macho world of STEM is a great place to start.

I can tell you with authority that when I'm exhausted, when I'm running on empty, I'm the worst version of myself.

Every launch of a new international edition of HuffPost is an opportunity to revisit our core DNA and remind ourselves who we are as an organization.

I get asked all the time how much sleep I get. That's what happens when you write a book called 'The Sleep Revolution,' travel around the world talking about it, and found a company committed to ending our global burnout crisis.

My passion is to help people live lives with less stress.

The middle class is teetering on the brink of collapse just as surely as AIG was in the fall of 2009 - only this time, it's not just one giant insurance company (and its banking counterparties) facing disaster, it's tens of millions of hardworking Americans who played by the rules.

It feels like we have two threads running through our lives: one pulling us into the world to achieve, the other pulling us back to replenish us. These threads can seem at odds, but really, they enforce each other. It's not a trade-off between success and sleep.

I used to stay up, stupidly, to work, and I'd just eat to keep my eyes open. I wasn't even hungry - it was just a way to power through.

I've always been fascinated by dreams - mine are so vivid. I went through a period in my 20s when I wrote down my dreams every morning. Then life intervened, and I stopped doing it.

There's something sacred in all of us that we need to protect, and sleep is a way to connect with it, nourish it, and make it more present in our lives.

Women process stress differently. If we can change the workplace culture to make it more welcoming for women, we're also going to improve behavior, and we're going to improve outcomes.

When we take care of ourselves, we are more effective, we are more creative, and we are more successful in a broad definition of the word.

I declare an end to my day by removing my phone from my bedroom and putting it in a phone charging bed.

I think she's the foundation of everything I've done. I think, definitely, my mother's fear of failure helps make me more resilient and helps make me persevere.

The most important thing that we entrepreneurs have is our human capital. If we exhaust it, we make bad decisions.

We take better care of our smartphones than we do of ourselves - the phones are always recharged!

Increasingly, staying in the middle class - let alone aspiring to become middle class - is becoming a game of chance.

We need to accept that we won't always make the right decisions, that we'll screw up royally sometimes - understanding that failure is not the opposite of success, it's part of success.
