We should always have three friends in our lives-one who walks ahead who we look up to and follow; one who walks beside us, who is with us every step of our journey; and then, one who we reach back for and bring along after we've cleared the way.

Value everyone's contribution and treat everyone with respect.

Some of my best memories are sitting on my dad's lap, cheering on Olga and Nadia, Carl Lewis and others for their brilliance and perfection.

I've seen firsthand that being president doesn't change who you are. It reveals who you are.

Sometimes, it's just easier to say yes to that extra snack or dessert, because frankly, it is exhausting to keep saying no. It's exhausting to plead with our kids to eat just one more bite of vegetables.

We can make a commitment to promote vegetables and fruits and whole grains on every part of every menu. We can make portion sizes smaller and emphasize quality over quantity. And we can help create a culture - imagine this - where our kids ask for healthy options instead of resisting them.

My goal has always been to add value, not to be redundant, not to get in the way, but to do things that lift and move things forward in a very strategic and objective way so that there are real outcomes.
