Psychologist Robert Ornstein, PhD, author of The Psychology of Consciousness, commented,
“If you spend too much time being like everybody else,
you decrease your chances of coming up with something different.”
Neuropsychologist David Weeks, in his book Eccentrics: A Study of Sanity and Strangeness, lists many creative eccentrics
including William Blake, Alexander Graham Bell, Emily Dickinson, Charlie Chaplin, Ludwig Wittgenstein, Howard Hughes.
