Muslims are of course famous for their five prayer times a day, which has always inspired me. In March, I visited a former classmate who is now a Benedictine nun living in community, and she said they pray six times a day. I sat in on their 2 PM service, which was lovely. It inspired a simple, perhaps foolish and very phone-centered idea which has nevertheless worked well and helped me be more disciplined. I set my phone's alarm to ring at 6 AM, 9 AM, noon, 3 PM, and 6 PM. The 6 AM gets me up (if I didn't get up at 5:30 already) and reminds me to pray. The other four times signal times to pause and pray. Bedtime is just bedtime, and I'm used to praying then.
But what to pray? I've email files that I can access on my phone and select a prayer. Here is a wonderful site called "100 Prayers": http://www.prayingeachday.org/100Prayers.pdf I also copied some favorite prayers from prayer books and put those on email messages that I can also access on my phone---as well as messages from the prayer chain to which I belong.
All this has worked well and, more often than not, I'm startled during the day when the alarm rings because, sure enough, I was occupied with something and would've forgotten to pray at that hour if not reminded.
I throw these ideas out in case they're helpful to someone who, like me, aspires to frequent prayer but has busy days, things going on, and good intentions.
