It’s easy for me to pray for strangers because when I was with my Catholic grandmother as a kid she’d say “Look at that man/woman/child who looks as if they are struggling.” Let’s pray for them. She’d also tell me she was praying for me and others.
I also can pray for myself as as well and I do both quite a bit.
My problem is I can’t focus long enough now it seems to pray to the rosary. I used to pray it daily for years but I know God understands I do my best.
That’s my input, God bless.
