"Around the world, Gandhi, Nelson Mandela --..." - Quote by Barack Obama

“Environmentalism is not an upper-income issue, it's not a white issue, it's not a black issue, it's not a South or a North or an East or a West issue. It's an issue that all of us have a stake in. And if I can do anything to make sure that not just my daughter but every child in America has green pastures to run in and clean air to breathe and clean water to swim in, then that is something I'm going to work my hardest to make happen.”

“I am the eternal optimist. I think that, over time, people respond to civility and -- and rational argument.”

“I miss Saturday morning, rolling out of bed, not shaving, getting into my car with my girls, driving to the supermarket, squeezing the fruit, getting my car washed, taking walks.”

“I want to make a dent in the universe.”

“It's time to break our ties with anything in us that would rather complain about its situation than go to work to change it.”

“Change is like fire- if uncontrolled, it will consume us.”

“A hero is no braver than an ordinary man, but he is brave five minutes longer.”

“I never once made a discovery ... I speak without exaggeration that I have constructed three thousand different theories in connection with the electric light ... Yet in only two cases did my experiments prove the truth of my theory.”

“Unfortunately, sometimes you can't have fun accomplishing your goals. Sometimes people don't have the determination, the will, the steadfastness, the tenacity, they give in under the slightest struggle.”
