“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 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.William James first wrote about the curious warping and foreshortening of psychological time in his 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,” he wrote. “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, and the years grow hollow and collapse.” Life seems to speed up as we get older because life gets less memorable as we get older. “If to remember is to be human, then remembering more means being more human,” said Ed.”

“Many memory techniques involve creating unforgettable imagery, in your mind's eye. That's an act of imagination. Creating really weird imagery really quickly was the most fun part of my training to compete in the U.S. Memory Competition.”

“Someday in the distant cyborg future, when our internal and external memories fully merge, we may come to possess infinite knowledge. But that's not the same thing as wisdom.”

“No one who set out to design a form of communication would ever end up with anything like English, Mandarin, or any of the more than six thousand languages spoken today.”

“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.”

“One of the great challenges of our age, in which the tools of our productivity are also the tools of our leisure, is to figure out how to make more useful those moments of procrastination when we’re idling in front of our computer screens.”

“Our brains are obviously capable of astoundingly fast and complex calculations that happen subconsciously. We can't explain them because most of the time we hardly even realize they're happening.”

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

“A meaningful relationship between two people cannot sustain itself only in the present tense.”

“When we first hear [a] word, we start putting these associational hooks into it that make it easier to fish it back out at some later date.”

“Over the last few millennial, we've invented a series of technologies … that have made it progressively easier and easier for us to externalize our memories, for us to outsource this fundamental human capacity.”
