I’ve got forward momentum. There’s no virtue in it. It’s just a balancing act. I don’t dare stop. - Lois McMaster Bujold

“You go on. You just go on. There’s nothing more to it, and there’s no trick to make it easier. You just go on.”
“What do you find on the other side? When you go on?”
She shrugged. “Your life again. What else?”
“Is that a promise?”
She picked up a pebble, fingered it, and tossed it into the water. The moon-lines bloomed and danced. “It’s an inevitability. No trick. No choice. You just go on.”

“So much for that line of reasoning, Lord Richars,” Ekaterin finished. She sat back with a hand-dusting gesture, and added, by no means under her breath, “Twit.”

The man who assumes everything is a lie is at least as mistaken as the one who assumes everything is true. If no guarantee can suit you, perhaps the flaw is not in the guarantee, but in you.
