in youth

"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 weeks sooth themselves out into recollection to countless units and the years grow hollow and collapse."

William James, 1890
