The tedium of existence and feeling imprisoned in a deplorable job can cause a person to consider the most expedient escape route from suffering including flirting with suicide. Fernando Pessoa wrote in “The Book of Disquiet” of his own feelings of uneasiness and sense of discouragement. “I suffer from life and from other people. I cannot look at reality face to face. Even the sun discourages and depresses me. Only at night and all alone, withdrawn, forgotten, and lost, with no connection to anything useful or real – only then do I find myself comforted.

Sometimes the most remarkable things seem commonplace. I mean, when you think about it, jet travel is pretty freaking remarkable. You get in a plane, it defies the gravity of an entire planet by exploiting a loophole with air pressure, and it flies across distances that would take months or years to cross by any means of travel that has been significant for more than a century or three. You hurtle above the earth at enough speed to kill you instantly should you bump into something, and you can only breathe because someone built you a really good tin can that has seams tight enough to hold in a decent amount of air. Hundreds of millions of man-hours of work and struggle and research, blood, sweat, tears, and lives have gone into the history of air travel, and it has totally revolutionized the face of our planet and societies.But get on any flight in the country, and I absolutely promise you that you will find someone who, in the face of all that incredible achievement, will be willing to complain about the drinks.The drinks, people.That was me on the staircase to Chicago-Over-Chicago. Yes, I was standing on nothing but congealed starlight. Yes, I was walking up through a savage storm, the wind threatening to tear me off and throw me into the freezing waters of Lake Michigan far below. Yes, I was using a legendary and enchanted means of travel to transcend the border between one dimension and the next, and on my way to an epic struggle between ancient and elemental forces.But all I could think to say, between panting breaths, was, 'Yeah. Sure. They couldn’t possibly have made this an escalator.

I think at the heart of so much restlessness of the day is a spiritual vacuum. There is a yearning for meaningful lives, a yearning for values we can commonly embrace. I hear an almost inaudible but pervasive discontent with the price we pay for our current materialism. And I hear a fluttering of hope that there might be more to life than bread and circuses.

I know about me. I am the moons sister, a tidal child stranded on land. The sea always in my ear, a surf of eternal discontent in my blood.

In the meantime the strike is over, with a remarkably low loss of life. All is quiet, they report, all is quiet.In the deserted harbour there is yet water that laps against the quays. In the dark and silent forest there is a leaf that falls. Behind the polished panelling the white ant eats away the wood. Nothing is ever quiet, except for fools.

...No matter how much Theo achieves and acquires and out-dazzles everyone else, she never seems content. She's taught you that people who shine more lavishly that everyone else seem to be penalized by discontent, as if they're being punished for craving a brighter life. I've been knocked down so many times I can't remember the number plates, she said once.

Back at home, days later, feel cranky and tired. Sit on the couch and tell him he's stupid. That you bet he doesn't know who Coriolanus is. That since you moved in you've noticed he rarely reads. He will give you a hurt, hungry-to-learn look, with his James Cagney eyes. He will try to kiss you. Turn your head. Feel suffocated. (from 'How').

Fiction can show you a different world. It can take you somewhere you've never been. Once you've visited other worlds, like those who ate fairy fruit, you can never be entirely content with the world that you grew up in. Discontent is a good thing: discontented people can modify and improve their worlds, leave them better, leave them different.

— Neil Gaiman
