If you are close friends with priests you quickly realize that the 24/7 nature of their vocation leaves no room for a vocation to marriage as well. The happiest, holiest priests I know well understand this and willingly make the sacrifice for God and for the rest of us.
Baloney. Owning your own business is a 24/7 job and is much more difficult than being a priest. Yet many entrepreneurs are married. No disrespect intended, but I can think of dozens of jobs that are far more demanding than being a priest.
