This definitely makes you think about the sense of child-like optimism that we all had (or still have if we're lucky), and the role it plays in our success. Entrepreneur and conscious capitalist, Chip Conley, has an interesting take on the connection:
Great leaders are one part childhood idealism and one part adult practicality. Unfortunately, many of us get a little too carried away with the latter. Again, if you follow your calling with passion, I believe you'll connect with that childhood idealism. I also use great quotes as inspirations on a daily basis.
