This is a letter from the Archbishop of Omaha, Nebraska to the priests in his diocese exhorting and encouraging them in the daily recitation of the office, but I think it speaks to anyone who prays the office. Or to anyone who is interested in understanding what the office is and why the church prays it.
Of course, lay persons are not required to pray the office, but they are encouraged to do so. The liturgy of the hours is the universal prayer of the Church.
I need as much encouragement as I can get, so I found these words to be quite helpful.
