Don't betray your dreams for the sake of fitting in. Dreaming is one of humanity's greatest gifts – it champions aspiration, spurs innovation, leads to change, and propels the world forward.

We should all dream, and encourage others to do so too. In a world without dreams there would be no art, no adventure, no moon landing, no female CEOs, and no civil rights. What a half-lived and tragic existence we would have. 

Speaking on the importance of dreaming, American entrepreneur, author and humanitarian activist, Dan Pallotta said: "I believe that dreams, taken seriously… are the most sophisticated things known to humanity… A great dream drives innovation – it doesn't happen the other way around. A great dream drives collaboration – it doesn't happen the other way around."

Don't be self-conscious about dreaming, or about people thinking you're too idealistic, and not serious enough. Don't allow your self talk to be judgmental. Look at the world with wide-eyed enthusiasm, believe you are more powerful than the problems that confront you, and dream big.
