“Monotony collapses time; novelty unfolds it. You can exercise daily and eat healthily and live a long life, while experiencing a short one. If you spend your life sitting in a cubicle and passing papers, one day is bound to blend unmemorably into the next - and disappear. That's why it's so important to change routines regularly, and take vacations to exotic locales, and have as many new experiences as possible that can serve to anchor our memories. Creating new memories stretches out psychological time, and lengthens our perception of our lives.”

“Monotony collapses time. Novelty unfolds it.”

“William James wrote (in Principles of Psychology in 1890): "In youth we may have an absolutely new experience, subjective or objective, every hour of the day. Apprehension is vivid, retentiveness strong, and our recollections of that time, like those of a time spent in rapid and interesting travel, are of something intricate, multitudinous and long-drawn-out. But as each passing year converts some of this experience into automatic routine which we hardly note at all, the days and the weeks smooth themselves out in recollection to contentless units..." Life seems to speed up as we get older because life gets less memorable as we get older.”

“Our lives are the sum of our memories. How much are we willing to lose from our already short lives by … not paying attention?”

“How we perceive the world and how we act in it are products of how and what we remember...No lasting joke, invention, insight, or work of art was ever produced by an external memory...Our ability to find humor in the world, to make connections between previously unconnected notions, to create new ideas, to share in a common culture: All these essentially human acts depend on memory. Now more than ever, as the role of memory in our culture erodes at a faster pace than ever before, we need to cultivate our ability to remember. Our memories make us who we are. They are the seat of our values and source of our character. Competing to see who can memorize more pages of poetry might seem beside the point, but it's about taking a stand against forgetfulness, and embracing primal capacities from which too many of us have became estranged...memory training is not just for the sake of performing party tricks; it's about nurturing something profoundly and essentially human.”

“Forgotten phone numbers and birthdays represent minor erosions of our everyday memory, but they are part of a much larger story of how we've supplanted our own natural memory with a vast superstructure of technological crutches—from the alphabet to the BlackBerry. These technologies of storing information outside our minds have helped make our modern world possible, but they've also changed how we think and how we use our brains.”

“Our culture is an edifice built of externalized memories.”
