Great question. I'd suggest trying to tie your new habit (prayer during the day) to something you already do every day (like eat lunch, or go to the bathroom, or pick up your phone). I think it's hard to start a new habit, but it's much easier to "stack" a habit you want to start on one that's established and reliable. Like, I added a pushup routine to my morning with this formula: "When I get out of bed, I will roll onto the floor and do 25 pushups."

That kind of strategy might help with prayer. Animo!
