“A journey of a thousand miles begins with a single step.”

Change will not come if we wait for some other person or some other time. We are the ones we've been waiting for.

Say good words, think good thoughts, do good deeds.

We are the first generation to be able to end poverty, and the last generation that can take steps to avoid the worst impacts of climate change.

You can only fight the way you practice.

If you want to shine like a sun, first burn like a sun.

Nothing will work unless you do.

If it is in our power to prevent something bad from happening, without thereby sacrificing anything of comparable moral importance, we ought, morally, to do it.

Once you start working on something, don't be afraid of failure and don't abandon it.
