ALS in German, signed “A. Einstein,” one page, 5 x 6.75, March 26, 1923. Handwritten response to a solicitation for life advice from an American educator, in full (translated): "To save time is a wonderful quest if a person is able to make something wonderful out of it. Otherwise it's better to sit back and live comfortably and to be sure not to pack it with too many things to do as you would overpack your briefcase." In very good to fine condition, with light dampstaining and associated wrinkling to the top and bottom edges, not affecting the main body of text. Accompanied by the original mailing envelope and a full letter of authenticity from PSA/DNA.
Though Einstein packed his own life with many things to do—developing world-changing scientific theories, mentoring young physicists, and advocating for world peace—he also found time for leisure. Among his beloved hobbies were playing the violin, sailing, and reading. On the whole, Einstein's life was well balanced yet extraordinarily productive. A wonderful letter from the genius.
