I have always been rather amused at the "study for a year and a day". I have been studying for nigh on 80 years! And the more I study, the more I conclude that I don't know very much at all!
The great Sir Isaac Newton said much the same thing,He said,
*I think of all that I know is as that of a pebble on a beach. What I don't know is the rest of the beach!"
