"Some of us give up on life with only a resigned sigh. Others fight a little, then lose hope. Still others—and I’m one of those—never give up. We fight and fight and fight. We fight no matter the cost of battle, the losses we take, the improbability of success. We fight to the very end. It’s not a question of courage. It’s something constitutional, an inability to let go. It may be nothing more than life-hungry stupidity." (Yann Martel, Life of Pi)
