I do a full Rosary, all four sets of mysteries, every day.
I find time here and there; in the shower, while driving, while waiting for my wife, walking the dog, etc.
If I’m doing any of those above, I have to count on my fingers, which is fine.
I try to do it all at once, or at least on set of mysteries all at once using beads or a tenner ring, but it’s not always possible, so I’ll do a decade here and a decade there.
About 15 minutes for each set, so an hour total.
The graces and strength to my faith that I’ve received have been immeasurable.
