Medical researchers don't know much about head lice because they don't much care. The reason that they don't much care is, paradoxically, that they know a lot. That is, they know one important thing: there is no evidence that head lice transmit disease.

What is obnoxious about the motives of politicians - whatever those motives may be - is that politicians must announce their motives as visionary and grand.

I don't understand anything about America's culture.

We Americans, who invented traffic, are always being startled by the forms into which it has evolved around the world.

What Enron was doing, what caused investors to embrace it in a rapture of baffled awe, was hiding debt.

Regulation creates a moral hazard.

The whole melodrama of the Middle East would be improved if amnesia were as common here as it is in melodramatic plots.

Californians devised a system of electricity sales that ignored every dimension of the free market.

A 'farm' today means 100,000 chickens in a space the size of a Motel 6 shower stall.

TV ushered in the age of postliteracy. And we have gone so far beyond that. I mean, what with the Internet and Google and Wikipedia. We have entered the age of post-intelligence.

A person has got to balance work and life and family in order to be a balanced person.

If it were not for government regulation of big corporations, executives at companies like Enron, WorldCom, Tyco, they could have cheated investors out of millions.

We did not become libertarians because we are altruists.

You can't destroy America by destroying our elite. Think about America's elite. Think about it down through history. Destroy our elite, and about half the time, you're doing us a favor.

Any terrorism is an attack on libertarian values.

War diminishes both civil and economic rights.

Why do elites hate the poor? It's xenophobia. They don't know any poor people - except their off-the-books Brazilian nanny and illegal immigrant cleaning lady from Upper Revolta who don't speak English.

America is a meritocracy.

Your dreams are what define your individuality. They have the power to give you wings and make you fly high.

When you are injured, you need to strengthen yourself very well to make a comeback very confidently.

Fitness is the key. You need to have strokes and stamina and agility; you need to exercise really well. On-court and off-court are equally important.

There will be many obstacles in the pursuit of your dreams. I had long hours of training, balancing studies and badminton.

I have learnt many things, but there's more to learn. Every day is a new start.

If it makes me happy, it definitely adds to my well-being.

The key is not being overconfident. You should not think that because I'm a top-ranked player, I will win this game. You have to be focused.

Hard work is the key for success.

I went to school like any other regular student till Class VIII, and my favourite subject was math. From Class IX, things got a little difficult to manage. I was inclined towards studies, but then I also had to give time to badminton.

You win some and lose some. It's all part of the game. You have to take it in a very positive way.

Win or lose, I always focus only on giving my 100%.

You have to keep working all the time. How much you learn, there is always room for learning; you will have to keep improving all the time.

What hurts most is whenever I am leading, and then I lose the match, it is disappointing, and there are so many such matches.

Ups and downs will be happening; coming to the final and losing by a point or so should not matter.

Winning a tournament at the end of the year boosts your confidence a lot.

I didn't think I would have an Olympic medal at 21, but I knew I would give my best and play my game. I just viewed it as my first Olympics and that I would take it one match at a time, but to bring a silver home made me very, very happy.

My parents have been volleyball players, and my dad is an Arjuna awardee in volleyball.

I love dressing up, and I'm aware that people do say that it can take your attention away from the game. But I disagree with this notion!

While I am training, I don't go out for events, so rest days, in a way, take away that time. Apart from that, I just stay at home and rest, maybe relax at home and spend time with family.

It was important for me to get a super series title.

I am really lucky that I got such good coaches and everything I wanted, right from the infrastructure to proper coaching.

I love making friends and make others happy. But I also love to be happy all the time. All that aggression that you see remains on the court only.

I am aggressive only on court.

I am thankful to my parents. They have done many sacrifices.

Life has changed both on and off the court after the Rio Olympics medal. I have a lot of confidence on the court now and feel anything is possible. I also feel that I have improved my game. Off the court, I do get recognised more now.

I have a lot of hunger to win the big titles.

Playing for Hyderabad Hunters is a very good feeling.

Previously, people were like, 'She might win the tournament,' but now it's like, 'She should win the tournament.'

I was 18 when I was presented with the Arjuna Award. To say it feels really good would be an understatement. But I don't know how else to convey the feeling. I am grateful for having received this prestigious award at such a young age.

Each tournament is equally important.

Every tournament I have won has been memorable.

I will keep working on different aspects of my games. It's not so easy, and I need to work on every stroke.
