“A virtue is a habit that includes all of these things: actions (you take care of your child even when you don't feel like it), emotions (you are often overtaken by feelings of tenderness and delight), perceptions (you understand your little children better than they understand themselves), choices (you choose to get out of bed and go to the children's room even when you'd much rather not), and thoughts (you think differently, more thoroughly and carefully, about your children than about anyone else in the world). The habit of love includes all these things, but not necessarily all at the same time.”
