US President Barack Obama is celebrating his 54th birthday on Tuesday, 4 August. The democrat walked into the history books in 2008 by becoming the first African American president of the country.

On the occasion of his 54th birthday, here are some of his most inspirational quotes:

Now, as a nation, we don't promise equal outcomes, but we were founded on the idea everybody should have an equal opportunity to succeed. No matter who you are, what you look like, where you come from, you can make it. That's an essential promise of America. Where you start should not determine where you end up.

The best way to not feel hopeless is to get up and do something. Don't wait for good things to happen to you. If you go out and make some good things happen, you will fill the world with hope, you will fill yourself with hope.

If you're walking down the right path and you're willing to keep walking, eventually you'll make progress.

 I'm inspired by the love people have for their children. And I'm inspired by my own children, how full they make my heart. They make me want to work to make the world a little bit better. And they make me want to be a better man.

The future rewards those who press on. I don't have time to feel sorry for myself. I don't have time to complain. I'm going to press on.

If there's a child on the south side of Chicago who can't read, that matters to me, even if it's not my child. If there's a senior citizen somewhere who can't pay for their prescription, who has to choose between medicine and the rent, that makes my life poorer - even if it's not my grandparent. If there's an Arab-American or Mexican-American family being rounded up by John Ashcroft without benefit of an attorney or due process, I know that that threatens my civil liberties. And I don't have to be a woman to be concerned that the Supreme Court is trying to take away a woman's right, because I know that my rights are next. It is that fundamental belief - I am my brother's keeper, I am my sister's keeper - that makes this country work.
