• “The enemy of memory isn’t time; it’s other memories. Each new event needs to establish new relationships among a finite number of neurons. The surprise is that a faded memory doesn’t seem faded to you. You feel, or at least assume, that the full picture is there.” — David Eagleman
• “I know this much: that there is objective time, but also subjective time, the kind you wear on the inside of your wrist, next to where the pulse lies. And this personal time, which is the true time, is measured in your relationship to memory.” ― Julian Barnes, The Sense of an Ending
• “Time isn’t precious at all, because it is an illusion. What you perceive as precious is not time but the one point that is out of time: the Now. That is precious indeed. The more you are focused on time—past and future—the more you miss the Now, the most precious thing there is.” ― Eckhart Tolle, The Power of Now: A Guide to Spiritual Enlightenment
