One thought from this article:
priests must love to pray, and must help their people to pray

Like everything else, the best way to encourage people to do something
is to give an example

Do our people ever see priests praying, apart from at Mass?

It can be very convenient to have a private chapel/oratory in the priests' house, but maybe it's better to use the parish church (if next to or in same building as priests' quarters)....to give an example, and to encourage people to join in Liturgy of Hours etc

Jesus, you loved to pray. Please help all priests love to pray
