Saving our planet, lifting people out of poverty, advancing economic growth... these are one and the same fight. We must connect the dots between climate change, water scarcity, energy shortages, global health, food security and women's empowerment. Solutions to one problem must be solutions for all.

Europe and Africa share proximity and history, ideas and ideals, trade and technology. You are tied together by the ebb and flow of people. Migration presents policy challenges - but also represents an opportunity to enhance human development, promote decent work, and strengthen collaboration.

The explosion in access to mobile phones and digital services means that people everywhere are contributing vast amounts of information to the global knowledge warehouse. Moreover, they are doing so for free, just by communicating, buying and selling goods and going about their daily lives.

We have a legal and moral obligation to rid our world of nuclear tests and nuclear weapons.

We have a legal and moral obligation to rid our world of nuclear tests and nuclear weapons. When we put an end to nuclear tests, we get closer to eliminating all nuclear weapons. A world free of nuclear weapons will be safer and more prosperous.

My U.N. five-point plan focuses on preventing proliferation, strengthening the legal regime, and ensuring nuclear safety and security - an effort that was given good momentum by the Nuclear Security Summit held in Seoul earlier this year. The world is over-armed, and peace is underfunded.

Terrorism is a significant threat to peace and security, prosperity and people.

Some might complain that nuclear disarmament is little more than a dream. But that ignores the very tangible benefits disarmament would bring for all humankind. Its success would strengthen international peace and security. It would free up vast and much-needed resources for social and economic development. It would advance the rule of law.

The burden for achieving disarmament cannot be borne by peace groups alone. Everybody, regardless of age, income, profession, gender or nationality, has a stake in this quest.

Nuclear disarmament and non-proliferation are not utopian ideals. They are critical to global peace and security.

Climate change, in some regions, has aggravated conflict over scarce land, and could well trigger large-scale migration in the decades ahead. And rising sea levels put at risk the very survival of all small island states. These and other implications for peace and security have implications for the United Nations itself.

I was profoundly moved to be the first United Nations Secretary-General to attend the Peace Memorial Ceremony in Hiroshima. I also visited Nagasaki. Sadly, we know the terrible humanitarian consequences from the use of even one weapon. As long as such weapons exist, so, too, will the risks of use and proliferation.

Nuclear power plants must be prepared to withstand everything from earthquakes to tsunamis, from fires to floods to acts of terrorism.

Climate change is destroying our path to sustainability. Ours is a world of looming challenges and increasingly limited resources. Sustainable development offers the best chance to adjust our course.

As I prepare for my second term as Secretary-General, I am thinking hard about how we can meet the expectations of the millions of people who see the U.N.'s blue flag as a banner of hope. We have to continue our life-saving work in peacekeeping, human rights, development and humanitarian relief.

Not many countries establish a prize for peace. The Seoul Peace Prize has its roots in the 1988 Summer Olympics when this country opened its doors to people and athletes from more than 160 countries. Korea did so in part because it believes in the power of sports for peace and development.

We are using resources as if we had two planets, not one. There can be no 'plan B' because there is no 'planet B.'

Grave security concerns can arise as a result of demographic trends, chronic poverty, economic inequality, environmental degradation, pandemic diseases, organized crime, repressive governance and other developments no state can control alone. Arms can't address such concerns.

This Earth is our only home. Together, we must protect and cherish it.

The possibility that terrorist groups could obtain weapons of mass destruction should not be dismissed as a fiction. This is a horrific threat the international community should take seriously. As long as these weapons exist, so, too, does the risk of their use - by accident or design.

If someone says 'grunge' or 'punk,' you know what the sound is, but if you say 'No Wave,' it's kind of mysterious. That was the most interesting part and should have been the most inspirational thing about it... here's this collective sonic insanity, and none of it sounds anything alike.

I believe happiness is a chemical imbalance - it's a silly thing to strife for. But satisfaction - if you seek satisfaction, you can succeed. Satisfaction is knowing that you're doing the best that you can do; you're living your life to the fullest.

I think my speeches are hilarious. I think I'm a natural comedian, but I like denying people the chance to laugh. I want to deny you the relief of the punchline.

Strange as it may seem, no amount of learning can cure stupidity, and formal education positively fortifies it.

Being appointed as the next Gewandhauskapellmeister of the Gewandhausorchester is a completely overwhelming honour. This extraordinary orchestra and its wonderful musicians are unique in so many respects, and particularly in their creation of an exceptional sound world based on outstanding tradition that is, at its heart, inspirational.

I'm thankful to Deutsche Grammophon, our partners - we are going to record the complete Shostakovich symphonies and hopefully some other things as well.

For a gallant spirit there can never be defeat.

A woman's life can really be a succession of lives, each revolving around some emotionally compelling situation or challenge, and each marked off by some intense experience.

I never make a trip to the United States without visiting a supermarket. To me they are more fascinating than any fashion salon.

I have always had the courage for the new things that life sometimes offers.

I am sure my fellow-scientists will agree with me if I say that whatever we were able to achieve in our later years had its origin in the experiences of our youth and in the hopes and wishes which were formed before and during our time as students.

Thanking you once more, I want to wish you the best of luck for your future life and to conclude by saying to you: Dream your dreams and may they come true!

Hope is some extraordinary spiritual grace that God gives us to control our fears, not to oust them.

We cannot go alone to God. We belong to His Mystical Body, the Church; by even our most secret sins, if they be grievous, we have injured the Mystical Body of Jesus Christ and must ask forgiveness of His Mystical Body, too.

As you are not yet married, and as marriage is the fundamental state of life as well as the unity of the commonwealth, make up your mind whether you are called to this state. If you make up your mind to marry, do not marry merely a good wife: marry a good mother to your children.

I look up to a strong woman; maybe that's why I fell for Gaga. She works incredibly hard and is very strong and inspirational like Mom, with a great work ethic.

To me, the most romantic gesture is a quiet night with my girl. I like to cook for her. I'm a meat eater and a griller - I do steaks, I do chicken, I do fish. I have a broad palate!

My mum wants me to get married - and have children, of course. She's met Gaga; we've been dating a while. We're in a committed relationship, and I'm really happy in my relationship. I'm a very lucky guy. As far as having more of a domestic life and settling down into my relationship, we have to see what happens.

Children have to be educated, but they have also to be left to educate themselves.

The happiness of most people is not ruined by great catastrophes or fatal errors, but by the repetition of slowly destructive little things.

By experience we find out a short way by a long wandering.

It is costly wisdom that is bought by experience.

Learning teacheth more in one year than experience in twenty.

Think with your whole body.

I think Spain will always remain inspirational, and I think French cuisine will continue to be very French and yet very relevant with its time and keep evolving. But the last thing you want for it is to become too trendy and confusing. It has too much history.

For me, good service is efficient and discreet; it's that critical balance. As soon as the client sits down, the communication flow has to start. Customers need to feel that the waiters are supervised - that there's a system in place.

I love to create, and to me, the ultimate freedom of expression is a blank canvas or a block of clay to capture whatever emotions your imagination gives it.

To me, there's no great chef without a great team.

When France was the only reference for chefs to learn, you could go everywhere in the world, and they would copy dishes directly because they didn't have much expanded imagination or technique or knowledge.

From Japan to Thailand, I keep discovering amazing talent, cuisine and food markets.
