I haven't been a leader - not at all.
This week we saw progressive business and faith leaders making strong commitments that are moving ahead of what world leaders promised today. The leaders of major economies must be bolder than they were today in providing a vision for 100% renewable energy for all.
The city of Copenhagen is a climate crime scene tonight, with the guilty men and women fleeing to the airport in shame. World leaders had a once in a generation chance to change the world for good, to avert catastrophic climate change. In the end they produced a poor deal full of loopholes big enough to fly Air Force One through.
My final advice for young people is to not wait for leadership from adult politicians. Step forward today, because our current leaders are denying the dire reality we are facing. Leadership can come form anywhere.
Nelson Mandela was just a human being, a person like other people, and everyone relaxed. Within a minute, that sort of thing about the leader and the lead, the gap was closed, and that's a rare thing.
Currently, we allow our political and business leaders to get away with murder. Now is the time to change that. We need direct liability for those who are destroying our future and this planet. We need fast, profound and systemic change. History only moves forward when courageous people get up and act. That's why I support this citizens' initiative to recognise ecocide as the crime it is.
The reality is today most of our political leaders want to be treated as gods and semi-gods, from the security details to the fuss around them and so on.
If you're the band leader you ask more of yourself than anyone else, so they tend to raise the bar for me.
A person who sins neither in thought nor deed, and is fair and just, gains enormous courage and strength. As a leader, you need courage born of integrity in order to be capable of powerful leadership. To achieve this courage, you must search your heart, and make sure your conscience is clear and your behavior is beyond reproach.
I have never received full credit from the SPLA [Sudanese People's Liberation Army], because the men are very sexist and feel that I'm acting out of place, bringing too much attention to myself - but for the funeral of our leader John Garang, they had me write the poem "Chol Apieth" to eulogize him, and that was their way of acknowledging my contributions.
I have always believed that on important issues, the leaders must lead. Where the leaders fail to lead, and people are really concerned about it, the people will take the lead and make the leaders follow.
I did not always achieve what I set out to do. Nevertheless, my personal example certainly suggests that hands-on experience can be helpful to future leaders.
One of my biggest regrets was the fact that as an institution and an international community we could not stop the war in Iraq. That really was very difficult and very painful. Every fibre in my body felt it was wrong. I spoke to leaders, we spoke to people, we tried... we couldn't stop it... and we see the results.
The world has lost a visionary leader, a courageous voice for justice, and a clear moral compass. By showing us that the path to freedom and human dignity lies in love, wisdom and compassion for one another, Nelson Mandela stands as an inspiration to us all.
Many African leaders refuse to send their troops on peace keeping missions abroad because they probably need their armies to intimidate their own populations.
The question is the morning after. What sort of Iraq do we wake up to after the bombing? What happens in the region? What impact could it have? These are questions leaders I have spoken to have posed.
It is tragic that so few young people in Western democracies vote. They have forgotten that their ancestors fought for the right to choose and change their leaders. They don't realise that their votes are more important than their tweets or Facebook posts.
I think the generational change is going to be so important for Africa that we really should encourage and push it as much as we can, because some of these younger men and women, who are men and women of their times, and are also connected to the rest of the world, wouldn't even know how to behave in the way some of the old leaders do.
The topic of leadership is a touchy one. A lot of leaders fail because they don't have the bravery to touch that nerve or strike that chord. Throughout my years, I haven't had that fear.
Being a leader, it's the art of trying to find the balance, the right times with each individual and what they need at that moment. It requires looking outward as opposed to looking inside.
Leaders are like eagles... they don't flock. You'll find them one at a time.
A great leader has brains, vision, soul, values and a heart.
There is a difference between being a leader and being a boss. Both are based on authority. A boss demands blind obedience; a leader earns his authority through understanding and trust.
I believe transparency in government is key to restoring our nations faith in its elected leaders.
Everybody knows how complicated this country's relationship with France has been, in war and in peace. Certainly there have been times when the leaders of France could have done better by us. We should have done better by them on Sunday. Only you couldn't find us.
Although the Great Leader told us that we have to let the people eat rice with meat soup, wear silk clothes and live in a tiled roof house, we have not accomplished his will.... We have already reached the status of a strong country in the military field, let alone politics and ideology, but there are still quite a number of things lacking in people's lives. I am trying to implement his will by solving these problems.
The core in the Juche outlook on the revolution is loyalty to the party and the leader. The cause of socialism and communism is started by the leader and is carried out under the guidance of the party and the leader.
It is a real tragedy for a nation when three groups of it's people, namely politicians, religious leaders and charity workes, just pretend to be generous.
The ageless melody, unheard, heals; the healing vision, unseen, leads; the true leaders, immortal, know....
I conclude where I began, I was elected by the people of Australia to do a job. I was not elected by the factional leaders of Australia, of the Australian Labor Party to do a job - though they may be seeking to do a job on me, that's a separate matter. The challenge therefore is to honour the mandate given to me by the Australian people.
My task, as a member of this parliament and a 30-year member of the Australian Labor Party, as its former leader, as its former foreign minister and its former prime minister, is to now throw my every effort in securing Julia Gillard's re-election as Labor prime minister at the next election.
A lot of people have said a lot of great things about Steve Jobs. And for good reason: he built the world's second-most valuable company, with billions in profits and products that have improved every aspect of our lives. But Steve didn't get there by being a soft, fluffy, Kumbaya-type leader.
Canada has always been ready for the truth. I think they actually appreciate a politician or anybody as a leader who tells the truth.
I don't think spending time in Ottawa is a good use of my time as the leader.
From these activists we can learn a crucial lesson: without citizens creating the institutions necessary for facilitating the growth of public deliberation, democracy will be a meaningless term. Without political leaders articulating this idea and acting upon it, public life and citizenship will continue to stagnate.
It is easier to recognize the quality of leadership in the behavior of their followers than it is in the behavior of the leader.
In 2007, Stanford Business School Advisory committee asserted that self awareness was the most important attribute a leader should develop. The challenge for the modern entrepreneur is to take that path.
Granuaile:"So why don't cult leaders achieve godhood?" Atticus:" Because they're megalomaniacs drenched in douche juice.
Deep down you know you can be remarkable. You shouldn't settle for anything less than your best self, reaching ever closer to your potential - whether as a leader or in any other part of your life.
When we become leaders, we sometimes think we are now supposed to have the answers. Yes, we may have some answers, but we will be more effective when we engage others and get their opinions.
