Steve Jobs Commencement Speech - Stanford University 2005 -

"...you can't connect the dots looking forward; you can only connect them looking backward. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever."  

"You've got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle."  

Thanks Louise for your answer.

As far as I know, it was selected as the best commencement speech ever. 

Bianca Toledo's. She tells her own real and unbelievable  personal story. She explain how she survived a terrible heallth problem and at no time she cries.because her speech is not meant to show her suffering, but a miracle. For those who understand Portuguese it can be found at YouTube.

The speeches of the British Labour Party veteran (Tony Benn) were very good. I respected that honest politician (a rare commodity these days!). I disagreed with him on certain issues but I learnt a lot from him and appreciated his courage & firm stand against injustice, racism, double standards, wars, and corruption. Two samples of his speeches:

Dear @Khaldoon, thanks for sharing this question. The following speech I was taught in school. Actually, it is about the officer of Serbian army, Major Dragutin Gavrilovic! The great war!

"Soldiers, exactly at three o'clock, the enemy is to be crushed by your fierce charge, destroyed by your grenades and bayonets. The honor of Belgrade, our capital, must not be stained. Soldiers! Heroes! The supreme command has erased our regiment from its records. Our regiment has been sacrificed for the honor of Belgrade and the Fatherland. Therefore, you no longer need to worry about your lives: they no longer exist. So, forward to glory! For the King and the Fatherland! Long live the King, Long live Belgrade!"

"The desperate charge that followed, in which Gavrilović was badly wounded, failed to destroy the Austro-Hungarian bridgehead. But the charge and similar acts of bravery and self-sacrifice by Serbian troops and by the inhabitants of Belgrade during the battle earned deep respect from the invaders, who suffered around 10,000 casualties in the course of capturing the city. The German commander August von Mackensen himself[citation needed] erected a monument on the battleground commemorating the city's zealous defenders; it still stands to this day and is inscribed with the words "Here Rest Serbian Heroes" in German and Serbian.

Gavrilović was awarded the Serbian war medal, Karadjordje's star, the French Croix de guerre, and many other medals..."

What a great words! Dear @Brenda, this is true patriotism!
