O, call not me to justify the wrong
That thy unkindness lays upon my heart

— Shakespeare, Sonnet 139

One of the hardest things a person can do is the same mundane task every day. It is not hard because the act of it is difficult, but because it must be done every day, and because there is no break from it. Art is certainly accomplished this way. Athletic training is accomplished this way. Good deeds that change the world are accomplished this way. Even harder, consider a task that no one else wants to do because it brings no glory, like the tasks that are usually asked of slaves, or parents. Anyway, it is summer. Not sure what I would do without Shakespeare.
