Advance Reading
It always helps me to focus at Mass if I have read the readings beforehand. It also helps to receive the daily readings in the Blessed Is She Devotion each morning! I usually click on the link in the email and read the readings, psalm and Gospel along with the thoughtful reflection based on them. You can subscribe to Blessed Is She here

The truth is…my hearing isn’t so great. I have a little trouble hearing the readings if the reader isn’t perfectly clear and if there is someone rustling a cough candy wrapper in the next pew. I find it much easier to focus if I’m following along with the readings as they are read.
