"It is not the end of the physical body that should worry us. Rather, our concern must be to live while we're alive - to release our inner selves from the spiritual death that comes with living behind a facade designed to conform to external definitions of who and what we are."
Elisabeth Kübler-Ross (Swiss-American psychiatrist and author)

"This above all, -- to thine own self be true; and it must follow, as the night the day, thou canst not then be false to any man."
William Shakespeare, Hamlet, Prince of Denmark
