Making your mark on the world is hard. If it were easy, everybody would do it. But it's not. It takes patience, it takes commitment, and it comes with plenty of failure along the way. The real test is not whether you avoid this failure, because you won't. it's whether you let it harden or shame you into inaction, or whether you learn from it; whether you choose to persevere.
Barack ObamaAnd to all those who have wondered if Americas beacon still burns as bright - tonight we proved once more that the true strength of our nation comes not from our the might of our arms or the scale of our wealth, but from the enduring power of our ideals: democracy, liberty, opportunity, and unyielding hope. For that is the true genius of America - that America can change. Our union can be perfected. And what we have already achieved gives us hope for what we can and must achieve tomorrow.
Barack Obama
