“The taking of life is too absolute, too irreversible, for one human being to inflict on another, even when backed by legal process. Where the death penalty persists, conditions for those awaiting execution are often horrifying, leading to aggravated suffering.”

For my generation, coming of age at the height of the Cold War, fear of nuclear winter seemed the leading existential threat on the horizon. But the danger posed by war to all humanity-and to our planet-is at least matched by climate change.

Millions of people in nearly 80 countries still live in fear of landmines and explosive remnants of war, which take an unacceptable toll on lives and limbs, and people’s livelihoods

I call for the need of world leaders to address climate change and reduce the increasing risk of disasters- and world leaders must include mayors, townships and community leaders.

Now, more than ever, we need to connect the dots between climate, poverty, energy, food and water. These issues cannot be addressed in isolation.

Nuclear terrorism is one of the most serious threats of our time. Even one such attack could inflict mass casualties and create immense suffering and unwanted change in the world forever. This prospect should compel all of us to act to prevent such a catastrophe.

We must turn the greatest collective challenge facing humankind today – climate change – into the greatest opportunity for common progress towards a sustainable future.

Nothing is more shameful than attacking sleeping children.

It is but a short step from hunger to starvation, from disease to death.

Sustainable development is the pathway to the future we want for all. It offers a framework to generate economic growth, achieve social justice, exercise environmental stewardship and strengthen governance.

We hold the future in our hands, together, we must ensure that our grandchildren will not have to ask why we failed to do the right thing, and let them suffer the consequences.

National boundaries these days are not that important because of transformative technological development. Now we are talking about the fourth industrial revolution.

Climate change…is, simply, the greatest collective challenge we face as a human family.

We have all heard of the web of life. The way we live threatens to trap us in a web of death.

You have to take ownership and leadership of tomorrow. For that to be possible, you have to strengthen your capacity and widen your vision as a global citizen.

The future of any leader or political systems is to be determined by the people of the country.

To measure the success of our societies, we should examine how well those with different abilities, including persons with autism, are integrated as full and valued members.

Today was about execution, period. Every single player, all of us in the dressing room right now, we’re embarrassed because that’s not the way we want to play soccer.

Deliberate before you begin; but, having carefully done so, execute with vigour.

It is not difficult to know a thing; what is difficult is to know how to use what you know.

The painter is, as to the execution of his work, a mechanic; but as to his conception and spirit and design he is hardly below even the poet.

There are really three parts to the creative process. First there is inspiration, then there is the execution, and finally there is the release.

If everybody trusts one another, then the person who didn’t prevail will faithfully execute the decision as if it was their idea.

Leaders honor their core values, but they are flexible in how they execute them.

Our emphasis is on execution, not winning.
