Since we started putting together our makeup collection, Kardashian Beauty, I've been extra invested in our list of no-no ingredients. It's an ingredients black list that we don't allow into the products - no parabens, no sulfates.

When I do my own makeup, I always start with Laura Mercier Tinted Moisturizer.

I've been applying makeup long enough to feel good doing it on my own, but I cannot do my hair to save my life. When left to my own devices, if I have to go to an event, I do a slicked bun. Otherwise, I just try to wear a hat, put it in a ponytail, or do a side braid - something easy.

We're definitely honest with each other... if your sisters can't tell you that you look ridiculous, who can?

Nothing comes before my children. I find that putting everything else in order of importance also helps to get everything done.

First dates are so awkward and annoying. I think a casual and fun first date with friends is much more fun than a one-on-one typical first date.

I don't think fame is that important to me.

We've always wanted to do a clothing line, and I personally love doing stuff with my sisters; I think it makes the whole process that much better.

I nursed Mason for 14 months and Penelope for 16, and I loved it. It was built-in time that the two of us could share alone every day. I didn't have any goals or expectations.

After Mason was born, I'd feel guilty doing anything that wasn't related to work.

After my daughter was born, I made a promise to myself to live in the moment.

I am obsessed with my sisters. Being the oldest, I probably just have that in me. But I also think I am the youngest sometimes. We all have moments when we are the maternal one of the group.

I feel that if I'm going through something, I'm sure someone else is, too.

I love and appreciate the bonding time with Mason. Nursing is surprisingly one of my favorite things.

I'm learning to trust other people to do things. My time is limited, and I'd rather be spending it with my kids.

The first thing I do when I'm shopping is touch everything to see if it's itchy. I remember my mom used to put me in the itchiest clothes ever, and I was traumatized by it, so I won't wear anything itchy now.

I actually hate when people open my gifts, and I hate opening gifts in front of people.

I know my mom always likes to give the over-the-top 'wow' pieces at baby showers.

Sometimes, it's hard to separate manager mode from mom mode. I think, as our manager, my mom will get more emotional about situations than she would if she was just our manager.

My mom fed us a lot of processed food when we were kids, like chicken fingers, grilled cheese sandwiches and quesadillas. I make those treats for my family, too, but I use organic cheeses and whole wheat bread and tortillas.

My kids' doctor will quickly answer any email, even if it's 11:00 at night. That's important to me.

One of my favorite things to do is go running early in the morning when everyone in my house is still sleeping. I throw on my iPod, and it's, like, my time.

I'm not a dating person.

I just got out of a nine-year relationship. I think the last thing I probably need is anybody in my life.

It is still crazy to me that I have two boys born on the same exact day. I really tried to not have it happen, so they could each have their day, but there was no way around it.

Mom always told us to wear pretty, matching underwear.

I don't want to judge, but I've also met women who think it's cool to be out or away from their baby, and I don't get that.

It was my first time taking a taxi with Mason. I had to tell the driver to wait because I had to get the stroller out of the car.

My mom bought me this amazing baby-food maker, the Beaba. I steam and puree fruits and vegetables, and they last for, like, four days.

Unless someone has walked in your shoes, you really can't judge. Everyone needs to make the best choice for their life.

I think motherhood is just about instinct.

When my younger sisters were born, I was in high school and college. I was at my mom's all the time but never changed them or fed them.

The robots are coming, whether we like it or not, and will change our economy in dramatic ways.

Political science has long tried to tackle a fundamental question of voter behavior: Do voters choose politicians because those politicians hold views that they like, or do voters choose policy positions because the politicians they like say those positions are correct?

There is nothing just or fair about what happened to Jordan Edwards. And his story is yet another in a long line of tragedies that now powerfully remind us of the long way we still have to go in creating a fair and just relationship between law enforcement, our criminal justice system, and the public our laws are supposed to protect.

I do not think it is a coincidence that young people gravitated toward populist voices in the French election and that the two issue positions where Donald Trump and young voters seem to agree most - global engagement and trade - are rooted in populism.

On paper, Emmanuel Macron should be a candidate tailor-made for young voters. He himself is young. He pushes for more entrepreneurship, modernization, and a loosening of regulations that prevent young workers from working as they please when they please.

What is a fair way to structure our economy? To handle those who did not come to America legally? To distribute scarce public resources and benefits?

Boosting STEM education opportunities for young women globally is one critical way that the U.S. can promote women's equality, as well as economic development, around the world.

It is fair to debate how much either bill - Obamacare in 2010, tax reform in 2018 - had or will have an impact on the midterms.

The data - on issues and on Trump himself - keep pointing back to 'one-in-four' as the true size of Trump's base. It is around one in four who like the tweeting, like the insults, the things other people say are mean or unproductive behavior.

Breaking dramatically with Bush-era Republican orthodoxy, Trump ran on a message of 'America First' and of avoiding spending blood and treasure on adventures overseas.

In 2012, when Mitt Romney named Russia as our greatest geopolitical foe, Democrats scoffed and accused Republicans of trying to ignite a new Cold War.

When polled on Donald Trump's agenda, though pluralities of young people oppose his policies on immigration and healthcare, there is one issue where Trump's position wins outright majority support, even among young Democrats: trade.

With an economy that is going strong and a belief that tomorrow will be better than today, it may be easier to just shrug it off if, say, an internet service you use like WhatsApp gets turned off by the government as the Communist Party's national congress approaches.

In the year 2000, the very youngest members of the Baby Boomer crew were in their mid-30s while the oldest Boomers were mid-50s. That year, the Boomers were a generation divided somewhat equally between the GOP and Democrats.

My dad is an electrical engineer. So he was always very focused on, you know, teaching his daughters about, you know, science, math, technology. None of us actually became engineers for our careers, but I always had that exposure when I was young, and I just loved playing computer games.

For thousands of years, humans have used the art of storytelling to motivate and persuade.

For Trump, the story is everything. There is no real plan to defeat the villains that Trump tees up, of course.

Polling is an art as well as a science, and the art of crafting good questions is still vital.
