“Life doesn't count for much unless you're willing to do your small part to leave our children – all of our children – a better world. Even if it's difficult. Even if the work seems great. Even if we don't get very far in our lifetime.”

“What I’ve realized is that life doesn’t count for much unless you’re willing to do your small part to leave our children — all of our children — a better world. Any fool can have a child. That doesn’t make you a father. It’s the courage to raise a child that makes you a father.”

“Today we begin in earnest the work of making sure that the world we leave our children is just a little bit better than the one we inhabit today.”

“This is the moment we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.”

“All of us - we should do everything we can to make sure this country lives up to our children's expectations.”

“This country of ours has more wealth than any nation, but that's not what makes us rich. We have the most powerful military on Earth, but that's not what makes us strong. Our universities and our culture are the envy of the world, but that's not what keeps the world coming to our shores. It is that American spirit - that American promise - that pushes us forward even when the path is uncertain; that binds us together in spite of our differences; that makes us fix our eye not on what is seen, but what is unseen, that better place around the bend”

“Our challenges may be new. The instruments with which we meet them may be new. But those values upon which our success depends - honesty and hard work, courage and fair play, tolerance and curiosity, loyalty and patriotism - these things are old. These things are true. They have been the quiet force of progress throughout our history. What is demanded then is a return to these truths. What is required of us now is a new era of responsibility - a recognition, on the part of every American, that we have duties to ourselves, our nation, and the world, duties that we do not grudgingly accept but rather seize gladly, firm in the knowledge that there is nothing so satisfying to the spirit, so defining of our character, than giving our all to a difficult task.”
