As I said in my State of the Union address ensuring the security of the United States and the safety of our people demands a smart, patient and disciplined approach to the world.

You can’t let your failures define you. You have to let your failures teach you.

Change will not come if we wait for some other person or some other time. We are the ones we've been waiting for. We are the change that we seek.

Keep exploring. Keep dreaming. Keep asking why. Don’t settle for what you already know. Never stop believing in the power of your ideas, your imagination, your hard work to change the world.

When ignorant folks want to advertise their ignorance, you don't really have to do anything, you just let them talk.

Just because we have the best hammer does not mean that every problem is a nail.

Change is never easy, but always possible.

Don’t ever let anybody tell you that your efforts don’t matter or that your voice doesn’t count. Don’t ever believe that you can’t make a difference. You have.

Where you are right now doesn't have to determine where you'll end up.

Learning to stand in somebody else's shoes, to see through their eyes, that's how peace begins. And it's up to you to make that happen. Empathy is a quality of character that can change the world.

If somebody is different from you, that's not something you criticize, that's something that you appreciate.

The world wasn't going to go away. Ever.

Before language, cavemen simply grunted, and then they used the club. Communication changed that. It's the mechanism that created civilization and prevents its own destruction.

The problem is when you are writing something in retrospective, it needs a lot of courage not to change, or you will forget a certain reality, and you will just take in consideration your view today.

I couldn't imagine not playing basketball. To me, basketball is what life is all about.

You might have a warrior spirit in there somewhere, and it's just waiting for the opportunity to come out. If you do, you might be a candidate for the pathway to enlightenment.

When souls really touch, it is forever. Then space and time disappear, and all that remains is the consciousness that we are not alone in life.

I can't stomach any kind of notion that serious fiction is good for us, because I don't believe that everything that's wrong with the world has a cure.

It is a good thing to write for the amusement of the public, but it is a far higher and nobler thing to write for their instruction, their profit, their actual and tangible benefit.

No one can go back, but everyone can go forward. And tommorow, when the Sun rises, all you will have to say to yourself is: I am going to think of this day as the first day of my life.

One reason people never attempt new things is their fear of failure.
