“It may seem difficult at first, but everything is difficult at first.”

For Europe, for ourselves, and for humanity, comrades, we must turn over a new leaf, we must work out new concepts, and try to set afoot a new man.

Nothing will work unless you do.

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

To know and not to act is not yet to know.

Sustainable development is the pathway to the future we want for all.

If you don't like someone's story, write your own.

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

Well done is better than well said.
