I know that millions of Americans from all walks of life agree with me that leadership does not mean putting the ear to the ground to follow public opinion, but to have the vision of what is necessary and the courage to make it possible.

It often takes more courage to change one's opinion than to keep it.

'The Impossible Dream' is, in my opinion, one of the greatest songs ever written. Here is a man, an old man, a very old man full of daring, bravery, courage, determination, romanticism and dreams.

Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition.

While I can hold my own with great talents and have an opinion in the face of big personalities, I'm just a regular guy. I've accepted my position in life: that I'm never going to be that cool. And I'm okay with that.

In the end, the whole Internet thing kills me, because you can use it as a positive thing or you can read into all the negativity. And I think you've gotta put out positive energy, put out cool viral stuff, and then just stay out of people's opinions.

If you want to eat pizza, have the pizza. If you want to run 5 miles up a hill, cool, go run. Do whatever you want to do, but don't let the size of your body and other people's opinions about you stop you from living the life you deserve.

You can never go wrong with a pair of jeans, a cool tailored shirt, and a nice jacket. You can dress it up with a more stylish jacket or a bracelet, watch, or necklace. It's simple, but it's cool. That's my opinion.

The computer is not, in our opinion, a good model of the mind, but it is as the trumpet is to the orchestra - you really need it. And so, we have very massive simulations in computers because the problem is, of course, very complex.

Computers and the Internet have made it really easy to rant. It's made everyone overly opinionated.

Coach Pederson, for me, the communication we have is clear, and it's an open line. He really respects my opinion on plays. If I'm feeling something... he instills a lot of confidence in me. That is huge.

A man has a property in his opinions and the free communication of them.

Characters do not change. Opinions alter, but characters are only developed.

Cinema builds memories; great films continue to exist in the spectator's mind. We are naturally capable of and prone to nostalgia. A spectator will reconstruct a film he or she has seen, years later, and may even change their original opinion. One critic, for example, once gave the finger to one of my films; later he wrote me to apologize.

For having lived long, I have experienced many instances of being obliged, by better information or fuller consideration, to change opinions, even on important subjects, which I once thought right but found to be otherwise.

There are two kinds of fools: those who can't change their opinions and those who won't.

Change your opinions, keep to your principles; change your leaves, keep intact your roots.

When people express opinions that differ from yours, take it as a chance to grow. Seek to understand over being understood. Be curious, not defensive. The only way to disarm another human being is by listening.

Opinions cannot survive if one has no chance to fight for them.

I have never entered into any controversy in defense of my philosophical opinions; I leave them to take their chance in the world. If they are right, truth and experience will support them; if wrong, they ought to be refuted and rejected. Disputes are apt to sour one's temper and disturb one's quiet.

Education must lead us from the irresponsible opinion to true responsible judgment. It must lead us from chance and arbitrariness to rational clarity and intellectual order. Therefore, let us guide our students over the road of discipline from materials, through function, to creative work.

My husband is pretty particular about his cars. In his opinion, the Mercedes are the best of the best.

Deprived of the opportunity to judge one another by the cars we drive, New Yorkers, thrown together daily on mass transit, form silent opinions based on our choices of subway reading. Just by glimpsing the cover staring back at us, we can reach the pinnacle of carnal desire or the depths of hatred. Soul mate or mortal enemy.

My opinion is it's a bridge too far to go to fully autonomous cars.
