“Hope,... which whispered from Pandora's box after all the other plagues and sorrows had escaped, is the best and last of all things. Without it, there is only time. And time pushes at our backs like a centrifuge, forcing outward and away, until it nudges us into oblivion... It's a law of motion, a fact of physics..., no different from the stages of white dwarves and red giants. Like all things in the universe, we are destined from birth to diverge. Time is simply the yardstick of our separation. If we are particles in a sea of distance, exploded from an original whole, then there is a science to our solitude. We are lonely in proportion to our years.”

“I knew I was alone in a way that no earthling has ever been before.”

“Can I join you at lunch?"  She paused. "You have every other day."  He laughed, a sound as musical as the chiming song of the lupine fey when they ran. "Yes. But you resented it every other day." 
"What makes you think I won't resent it today?"  "Hope. It's what I live on...”

“No one knows for sure that that tomorrow won't come,  but most people assume that tomorrow will still exist as usual.  This is Toba's Paradox, which means, hope overcomes doubt.”

“I'm really hoping he’s being genuine because I can already tell he isn't the kind of guy a girl gets a simple crush on. He’s the kind of guy you fall hard for, and the thought of that terrifies me. I don’t really want to fall hard for anyone at all, especially someone who’s only making an effort because he thinks I'm easy. I also don’t want to fall for someone who has already branded himself hopeless. But I'm curious. So curious.”

“One of the gravestones in the cemetery near the earliest church has an anchor on it and an hourglass, and the words In Hope.
In Hope. Why did they put that above a dead person? Was it the corpse hoping, or those still alive?” 
― Margaret Atwood

“Fair as the moon and joyful as the light; Tot wan with waiting, not with sorrow dim; Not as she is, but was when hope shone bright; Not as she is, but as she fills his dreams.” 
― Christina Rossetti
