All the world's a stage, and all the men and women merely players.
The only joy in this life is to act.
Follow your bliss, (Joseph Campbell)
Do your will, (Aleister Crowley)
Be true to yourself, (origin unknown)
live and let live (origin unknown).
"But what if my true self is evil?"
If it were so, would you ask this question?
The sickness of the world lies in the dissonance of its participants,
how absurd it is that anyone need be told to "be themselves".
