To know that you do not know and to be willing to admit that you do not know without sheepishly apologizing is real strength and sets the stage for learning and progress in any endeavor.
EpictetusIt is the act of an ill-instructed man to blame others for his own bad condition; it is the act of one who has begun to be instructed, to lay the blame on himself; and of one whose instruction is completed, neither to blame another, nor himself.
EpictetusThe wise realize that some things are within their control, and most things are not. They learn early on to distinguish between what they can and can't regulate.
