Instead of "Be yourself" I would suggest "Own yourself". Take ownership of your mind, actions, personality, failures etc. There are lot of invisible tentacles sucked into your thinking process.

> It is possible I can make very little of myself; but this little is everything, and better than what I allow to be made out of me by the might of others, by the training of custom, religion, the laws, the State. -- Max Stirner

As a side note, Max Stirner has a great book called "The Ego and His Own". Gives a quite radical but refreshing view on individualism.
