'The paths we take sometimes lead us away from people we know and
love. But in the end what matters is that we affect the lives of
others for the better somehow, whomever we are, whatever our story.
Obsession always destroys what it intended to nurture: but if
you're able to let yourself love honestly and without fear, maybe
that huge heart you have will somehow set you free.' - Eve Lockhart
