I just read something really brilliant:
Order, I think, should be an end in itself. Its “goal” should be something wholly abstract and transcendent, like cultivating a “love of God”, if you are inclined towards such things. The orderly lives of monks are not intended to make them more efficient or productive (though they no doubt get their chores done). If they read, write, pray and exercise every day it is because order as such is valuable to them. Their submission to God is simply realized in their submission to the disciplined life of a monastery. It is this order itself that they seek.
I love order, routine, and a fixed schedule. But I find them very difficult to attain.
