Susan Cain's book is a better book on creativity than Lehrer's Gladwell-style 'Imagine: How Creativity Works'. The main idea of  'Quiet' is that there is nothing wrong with being an introvert - nothing wrong about choosing listening over speaking, reading over partying; innovating and creating without needing to self-promote; and choosing working on their own over brainstorming in teams.

Remember, Van Gogh was an introvert, so were the inventor of the personal computer, founders of Google, author of Harry Potter books, Einstein, Newton, Chopin, creator of Peanuts, ...the list goes on.

Gandhi said, "In a gentle way, you can shake the world."
