On my sixteenth birthday I was in New York to speak at the United Nations. Standing up to address an audience inside the vast hall where so many world leaders have spoken before was daunting, but I knew what I wanted to say. ‘This is your chance Malala,’ I said to myself. Only 400 people were sitting around me, but when I looked out, I imagined millions more. I did not write the speech only with the UN delegates in mind; I wrote it for every person around the world who could make a difference. I wanted to reach all people living in poverty, those children forced to work and those who suffer from terrorism or lack of education. Deep in my heart I hoped to reach every child who could take courage from my words and stand up for his or her rights.

I wore one of Benazir Bhutto’s white shawls over my favourite pink shalwar kamiz and I called on the world’s leaders to provide free education to every child in the world. ‘Let us pick up our books and our pens,’ I said. ‘They are our most powerful weapons. One child, one teacher, one book and one pen can change the world.’ I didn’t know how my speech was received until the audience gave me a standing ovation. My mother was in tears and my father said I had become everybody’s daughter.

Something else happened that day. My mother allowed herself to be publicly photographed for the first time. As she has lived her life in purdah and never unveiled her face on camera before, it was a great sacrifice and very difficult for her.

At breakfast the next day Atal said to me in the hotel, ‘Malala, I don’t understand why you are famous. What have you done?’ All the time we were in New York he was more excited by the Statue of Liberty, Central Park and his favourite game Beyblade!

After the speech I received messages of support from all over the world, but there was mostly silence from my own country, except that on Twitter and Facebook we could see my own Pakistani brothers and sisters turning against me. They accused me of speaking out of ‘a teen lust for fame’. One said, ‘Forget the image of your country, forget about the school. She would eventually get what she was after, a life of luxury abroad.’

I don’t mind. I know people say these things because they have seen leaders and politicians in our country who make promises they never keep. Instead things in Pakistan are getting worse every day. The endless terrorist attacks have left the whole nation in shock. People have lost trust in each other, but I would like everyone to know that I don’t want support for myself, I want the support to be for my cause of peace and education.

The most surprising letter I got after my speech was from a Taliban commander who recently escaped from prison. His name was Adnan Rashid and he used to be in the Pakistan air force. He had been in jail since 2003 for attempting to assassinate President Musharraf. He said the Taliban had attacked me not for my campaign for education but because I tried to ‘malign [their] efforts to establish the Islamic system’. He said he was writing to me because he was shocked by my shooting and wished he could have warned me beforehand. He wrote that they would forgive me if I came back to Pakistan, wore a burqa and went to a madrasa.

Journalists urged me to answer him, but I thought, Who is this man to say that? The Taliban are not our rulers. It’s my life, how I live it is my choice. But Mohammed Hanif wrote an article pointing out that the good thing about the Taliban letter was that many people claim I wasn’t shot yet here they were accepting responsibility.

I know I will go back to Pakistan, but whenever I tell my father I want to go home, he finds excuses. ‘ No, Jani, your treatment is not complete,’ he says, or, ‘These schools are good. You should stay here and gather knowledge so you can use your words powerfully.’

He is right. I want to learn and be trained well with the weapon of knowledge. Then I will be able to fight more effectively for my cause.

Today we all know education is our basic right. Not just in the West; Islam too has given us this right. Islam says every girl and every boy should go to school. In the Quran it is written, God wants us to have knowledge. He wants us to know why the sky is blue and about oceans and stars. I know it’s a big struggle – around the world there are fifty-seven million children who are not in primary school, thirty-two million of them girls. Sadly my own country Pakistan is one of the worst places: 5.1 million children don’t even go to primary school even though in our constitution it says every child has that right. We have almost fifty million illiterate adults, two-thirds of whom are women, like my own mother.

Girls continue to be killed and schools blown up. In March there was an attack on a girls’ school in Karachi that we had visited. A bomb and a grenade were tossed into the school playground just as a prize-giving ceremony was about to start. The headmaster, Abdur Rasheed, was killed and eight children hurt between the ages of five and ten. One eight-year-old was left disabled. When my mother heard the news, she cried and cried. ‘When our children are sleeping we wouldn’t even disturb a hair on their heads,’ she said, ‘but there are people who have guns and shoot them or hurl bombs. They don’t care that their victims are children.’ The most shocking attack was in June in the city of Quetta when a suicide bomber blew up a bus taking forty pupils to their all-girls’ college. Fourteen of them were killed. The wounded were followed to the hospital and some nurses were shot.

It’s not just the Taliban killing children. Sometimes it’s drone attacks, sometimes it’s wars, sometimes it’s hunger. And sometimes it’s their own family. In June two girls my age were murdered in Gilgit, which is a little north of Swat, for posting a video online showing themselves dancing in the rain wearing traditional dress and headscarves. Apparently their own stepbrother shot them.

Today Swat is more peaceful than other places, but there are still military everywhere, four years after they supposedly removed the Taliban. Fazlullah is still on the loose and our bus driver still under house arrest. Our valley, which was once a haven for tourists, is now seen as a place of fear. Foreigners who want to visit have to get a No Objection Certificate from the authorities in Islamabad. Hotels and craft shops are empty. It will be a long time before tourists return.

Over the last year I’ve seen many other places, but my valley remains to me the most beautiful place in the world. I don’t know when I will see it again but I know that I will. I wonder what happened to the mango seed I planted in our garden at Ramadan. I wonder if anyone is watering it so that one day future generations of daughters and sons can enjoy its fruit.

Today I looked at myself in a mirror and thought for a second. Once I had asked God for one or two extra inches in height, but instead he made me as tall as the sky, so high that I could not measure myself. So I offered the hundred raakat nafl prayers that I had promised if I grew.

I love my God. I thank my Allah. I talk to him all day. He is the greatest. By giving me this height to reach people, he has also given me great responsibilities. Peace in every home, every street, every village, every country – this is my dream. Education for every boy and every girl in the world. To sit down on a chair and read my books with all my friends at school is my right. To see each and every human being with a smile of happiness is my wish.

I am Malala. My world has changed but I have not.
