“Women systematically underestimate their own abilities.”

There is no perfect fit when you’re looking for the next big thing to do. You have to take opportunities and make an opportunity fit for you, rather than the other way around. The ability to learn is the most important quality a leader can have.

I really think we need more women to lean into their careers and to be really dedicated to staying in the work force.

You know, there has never been a 24-hour period in five years when I have not responded to e-mail at Facebook. I am not saying it’s easy. I work long hours.

I have a five year-old son and a three year-old daughter. I want my son to have a choice to contribute fully in the workforce or at home. And I want my daughter to have the choice to not just succeed, but to be liked for her accomplishments.

Fortune does favor the bold and you’ll never know what you’re capable of if you don’t try.

I don’t pretend there aren’t biological differences, but I don’t believe the desire for leadership is hardwired biology, not the desire to win or excel. I believe that it’s socialization, that we’re socializing our daughters to nurture and our boys to lead.

I know from my own experience that the path to change is best traveled when we travel together.

Believe in yourself and negotiate for yourself. Own your own success.

The cost of stability is often diminished opportunities for growth.

Trying to do it all and expecting that it all can be done exactly right is a recipe for disappointment. Perfection is the enemy.

I feel really grateful to the people who encouraged me and helped me develop. Nobody can succeed on their own.

What I tell everyone, and I really do for myself is, I have a long-run dream, which is I want to work on stuff that I think matters.

Real empathy is sometimes not insisting that it will be okay but acknowledging that it is not.

Bring your whole self to work. I don’t believe we have a professional self Monday through Friday and a real self the rest of the time. It is all professional and it is all personal.

It’s more pressure on women to – if they marry or partner with someone, to partner with the right person. Because you cannot have a full career and a full life at home with your children if you are also doing all of the housework and child care.

But the upside of painful knowledge is so much greater than the downside of blissful ignorance.

I don’t think your ability to fight has anything to do with how big you are. It’s to do with how much anger is in you.

Abilities wither under criticism; they blossom under encouragement.

We are what we think we are. The habitual inclination of our thoughts determines our talents and abilities, and our personality. So whatever you want to be, start to develop that pattern now.

Faith in anything, be it positive or negative, produces results. Putting faith in fear generates destructive results, beginning with the disintegration of our ability to relate confidently to the external world.

Men who undertake considerable things, even in a regular way, ought to give us ground to presume ability.

As secretary of state it’s been an enormous honor to represent this great country that I love so much – I have really seen that our great strengths are in the ability of people to reach their potential here.

You don’t know what you can get away with until you try.

Until you love yourself, you will never know who you really are and you won’t know what you’re really capable of.
