Beth, geniuses are driven by a force within which they can't shake off.  However much they might resist, the voice doesn't go away--it reaches the point that makes them delirious or mad--that's when they realise the gift is a curse and they have to pay a price in suffering and torment.  They ask themselves: Is this worth the price?

Yet, it's their misery that gives the world the gift of infinite beauty, wonder and awe.  We are the benefactors of their suffering.
