I believe that all of us have a little bit of crazy in us, even if just a pinch. It could manifest out of extreme enthusiasm, foolish behavior or downright insanity. Aside from its legal concept, insanity or crazy is a personality trait, a neurotic emotional state that can surprisingly be beneficial to us in many ways--especially when it comes to creativity, increasing consciousness, as well as problem-solving. However, when your crazy outweighs your rationale, it is definitely time to seek professional help.
