What are the best quotes of Barack Obama?

The reason that Obama's quotes have resonance is that mostly they appeal for their sincerity, as opposed to 'telling' sentences written by a political speech writer. Here is one, Change will not come if we wait for some other person or some other time. We are the ones we've been waiting for. We are the change that we seek.

Another is, If you're walking down the right path and you're willing to keep walking, eventually you'll make progress. Simple, and ideas that any person can adopt.
