'...hope is not like a lottery ticket you can sit on the sofa and clutch, feeling lucky. I say this because hope is an ax you break down doors with in an emergency; because hope should shove you out the door, because it will take everything you have to steer the future away from endless war, from the annihilation of the earth's treasures and the grinding down of the poor and marginal. Hope just means another world might be possible, not promised, not guaranteed. Hope calls for action; action is impossible without hope... To hope is to give yourself to the future, and that commitment to the future makes the present inhabitable.' 
Rebecca Solnit, Hope in the Dark
