To a large degree, since the beginning of time, charisma or the lack of it has impacted upon those in quest of acclaim. As media expands, this has become ever more vital.

John DonneDoth not a man die even in his birth? The breaking of prison is death, and what is our birth, but a breaking of prison?
John DonneDeath be not proud, though some have called thee Mighty and dreadful, for thou art not so. For, those, whom thou think'st thou dost overthrow. Die not, poor death, nor yet canst thou kill me.
John Donne
