I have one myself. This was mostly because of the urging of fellow Catholics on a Catholic Facebook discussion group.
Some stated that, probably based on the nature of my posts there, that a spiritual director would be a good idea for me. Hence I went and found one.
So far it has been helpful. Unfortunately, my director seems to be a busy man and it has been awhile since I have been able to speak to him about my spiritual life (his parish used to have three priests but is now down to two…I think).
Pax Tecum.
