Relationships are personal, even in business, so sharing some of yourself and taking an interest in others helps to build trust and break down walls.

As people flock to urban centers where ground space is limited, cities with green walls and roofs and skyscraper farms offer improved health and well-being, renewable resources, reliable food supply, and relief to the environment.

I find it a bit sad that there is no photo of me hanging on the walls in the Berlin Museum at Checkpoint Charlie.

The walls we build around us to keep sadness out also keeps out the joy.

Kabul is a walled city, which sounds romantic except the walls are pre-cast reinforced concrete blast barriers, 10 feet tall and 15 feet long and moved into place with cranes. The walls are topped with sandbags, and the sandbags are topped with guard posts from which gun barrels protrude.

Dogs really are perfect soldiers. They are brave and smart; they can smell through walls, see in the dark, and eat Army rations without complaint.

Writing novels is largely about endurance and patience. I take a lot of breaks, hit walls, and go do something else while I think things through. But I do it every day, and I try to treat it as a job, something that is not dictated by whimsy or muses.

Reinforced concrete buildings are by nature skeletal buildings. No noodles nor armoured turrets. A construction of girders that carry the weight, and walls that carry no weight. That is to say, buildings consisting of skin and bones.

I don't like the idea that in music, clothes, taste or anything, we are limited to a certain style, because we need to maintain an identity, maybe between some subculture group. Hopefully, all those walls break down, and music is just music.

It's rare that I'm able to get to my desk in the morning without stopping halfway there, turning around, and going in the opposite direction because of a pressing need to straighten all the pictures on the walls, floss my teeth a second time, and make certain that there really are 100 postage stamps in the roll of stamps I bought yesterday.

A company can spend hundreds of thousands of dollars on firewalls, intrusion detection systems and encryption and other security technologies, but if an attacker can call one trusted person within the company, and that person complies, and if the attacker gets in, then all that money spent on technology is essentially wasted.

Companies spend millions of dollars on firewalls, encryption, and secure access devices and it's money wasted because none of these measures address the weakest link in the security chain: the people who use, administer, operate and account for computer systems that contain protected information.

I guess I figured out my dad was a fight coordinator pretty early, because I always saw him running into walls and stuff and nobody got mad at him, but it took me a lot longer to figure out what Mom did, because it was usually stuff on the telephone.

The fact is, when men carry the same ideals in their hearts, nothing can isolate them - neither prison walls nor the sod of cemeteries. For a single memory, a single spirit, a single idea, a single conscience, a single dignity will sustain them all.

The vote is the most powerful instrument ever devised by man for breaking down injustice and destroying the terrible walls which imprison men because they are different from other men.

Jesu's walls of distortion are uplifting in comparison to those of its doom-driven contemporaries. The band's 2009 album 'Infinity' has its bleak moments, but that album's single 49-minute song resolves into something inspirational and grandiose by the time it's over.

President Obama called for a 'we' nation in his Inauguration Address. Art convenes. It is not just inspirational. It is aspirational. It pricks the walls of our compartmentalized minds, opens our hearts and makes us brave. And that's what we need most in our country today.

In the United States today, the Declaration of Independence hangs on schoolroom walls, but foreign policy follows Machiavelli.

When you're even on a regular movie set, you still have to suspend your disbelief. You're working there with only 3 walls of a room, and you're in costume, and you have a camera 6 inches from you and have a crew of 75 watching you. So even there, you have to crank up your imagination.

Ideas come from ordinary, everyday life. And from imagination. And from feelings. And from memories. Memories of dust in my sneakers and humming whitewalls down a hill called Monkey.

Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring, those ripples build a current that can sweep down the mightiest walls of oppression and resistance.

If you look at the paintings that I love in art history, these are the paintings where great, powerful men are being celebrated on the big walls of museums throughout the world. What feels really strange is not to be able to see a reflection of myself in that world.

Working with plants, trees, fences and walls, if they practice sincerely they will attain enlightenment.

Every time I imagine a garden in an architectural setting, it turns into a magical place. I think of gardens I have seen, that I believe I have seen, that I long to see, surrounded by simple walls, columns, arcades or the facades of buildings - sheltered places of great intimacy where I want to stay for a long time.
