"If you ever get the chance, stop and lay on Einstein's couch" --- my father in law
Back story: my father in law used to deliver booze to a hotel near Caltech that Einstein used to stay at when he was a visiting Scientist. One day, he went into the hotel to drop off a delivery. He asked about Einstein's room and he was offered to visit the room. However being that he was in a hurry and on the clock, he decided to take a rain check. He never got to cash it in and now regrets that he never took the time to lay on Einstein's couch. Lesson learned, take the time to lay on Einstein's couch for you may never get that opportunity again.
