We often read that without being crazy, you cannot be creative; you have to unleash your crazy side to think creatively.
Most of the creative minds, from Van Gogh to Sylvia Plath, from Leonardo Da Vinci to Robert Schumann, all linked to at least one neurotic incident in their life, have created one of the best art of all time, be it music, painting, poems or any other form of art.
Often, the crazy ones are not seen as a part of society but rather as alien and foreign; these crazy ones are usually the artists.
