Keeping a relationship with the love of my life, for 16 years.

Building my mum her dream home.

Being happy. I think that transcends the results of my matches, the so-called successes or failures. How would you like to be remembered? As someone who dedicated their life to what they were doing at the time. Right now, it’s tennis, but I want to have the same dedication for whatever I do after, whether it be motherhood or another career.

That I turned a broken heart into a career. That I hit rock bottom and bounced back up a lot higher.

When I feel as if the people closest to me are happy and healthy and I'm connected with them, and when I feel as if I'm doing things that are making other people better and happy, then I feel real good. That's when I'm at my peak.

What makes me proudest about them is that they also don't get cynical about it. They have not assumed because their side didn't win, or because some of the values that they care about don't seem as if they were vindicated, that automatically America has somehow rejected them or rejected their values.

I was raised by a heroic single mom, wonderful grandparents -- made incredible sacrifices for me. … But I sure wish I had had a father who was not only present, but involved. Didn't know my dad. And so my whole life, I've tried to be for Michelle and my girls what my father was not for my mother and me. … I want to be a better father, a better husband, a better man.

There are some things about being president that I still have difficulty doing. … For example, faking emotion. Because I feel it is an insult to the people I'm dealing with. For me to feign outrage, for example, feels to me like I'm not taking the American people seriously. I'm absolutely positive that I'm serving the American people better if I'm maintaining my authenticity. And that's an overused word. And these days people practice being authentic. But I'm at my best when I believe what I am saying.

When I am on my deathbed, and I am thinking back on my life, I am absolutely certain that the thing I will be thinking about is holding my daughters' hands and taking them to the park. It will not be some speech I gave or some legislation that I passed. I am positive about that. And so if you keep that in mind, then you have to invest accordingly.

You'll see I wear only gray or blue suits. … I'm trying to pare down decisions. I don't want to make decisions about what I'm eating or wearing. Because I have too many other decisions to make. … You need to focus your decision-making energy. You need to routinize yourself. You can't be going through the day distracted by trivia.
