Know how to adapt yourself. You don’t need to appear equally intelligent to all, nor should you employ more effort than is necessary. With knowledge and excellence, nothing should be squandered. A good falconer releases only as many birds as are needed for the chase. Don’t continually fleeting your qualities or there’ll be nothing left to admire. There must always be something novel with which to dazzle, for people who reveal something new each day keep interest alive and never allow the limits of their great abilities to be discovered.
