I usually start with a big question, such as whether people today are happier than in the past, or why men have dominated women in most human societies. And then I follow the question instead of trying to follow my own answer, even if it means I can't formulate any clear theory.

How could someone with a renowned ability to inspire, communicate complex ideas, and connect with voters find himself in this position? The President [Barack Obama], though a dedicated student of history, has seemingly failed to learn the lesson of our nation's most significant political confrontations: They've required single-minded determination, and the willingness to battle until the fight was won.

It would be futile to attempt to fit women into a masculine pattern of attitudes, skills and abilities and disastrous to force them to suppress their specifically female characteristics and abilities by keeping up the pretense that there are no differences between the sexes.

Don't just climb the ladder, chart a new path.

Don’t just climb the ladder of success - a ladder that leads, after all, to higher and higher levels of stress and burnout - but chart a new path to success, remaking it in a way that includes not just the conventional metrics of money and power, but a third metric that includes well-being, wisdom, wonder and giving, so that the goal is not just to succeed but to thrive.

I wish I'd known sooner that success isn't defined by who goes the longest without vacation.

Money and power by themselves are a two-legged stool. You can balance on them for a while, but eventually you're going to topple over.
