“The worst loneliness is not to be comfortable with yourself.”
Mark Twain

“There is no greater sorrow, then to recall in misery the time we were happy.”
Dante

“The end comes when we no longer talk with ourselves. It is the end of genuine thinking and the beginning of the final loneliness. The remarkable thing is that the cessation of the inner dialogue marks also the end of our concern with the world around us. It is as if we noted the world and think about it only when we have to report it to ourselves."
Eric Hoffer

“There’s nothing terribly wrong with feeling lost, so long as that feeling precedes some plan on your part to actually do something about it. Too often a person grows complacent with their disillusionment, perpetually wearing their "discomfort" like a favourite shirt.”
Jhonen Vasquez

“There's a cold wind blowing softly through a narrow, dark ravine. A sound is heard, soft and everywhere, like the rustle of silk. It echoes from every dismal reaching corner of the abyss, and whispers of the aching loneliness within the crevasse. A cold, blue-white light transcends an aura of weird lifelessness to the jagged rocks of the cleft walls. There appears a soul within all of this, like a thin frail mist, congealing within its center -- a tiny translucent grey cloud.”
Ralph Kenyon, 1962

"We're born alone, we live alone, and we die alone. Only through our love and friendship can we create the illusion for the moment that we're not alone."
-Orson Wells

“The whole conviction of my life now rests upon the belief that loneliness, far from being a rare and curious phenomenon, peculiar to myself and to a few other solitary men, is the central and inevitable fact of human existence.”
-Thomas Wolfe
