Since I'm taking a break from classes for a year, I have a lot more free time. I only work 5 hours per day and I have Sundays off, so I find lots of time to practice formally, besides just being mindful throughout the day, practicing generosity, virtue and renunciation. It's hard for sure, and I fail a lot. But it makes my successes that much sweeter.
Every morning I chant homage to the Buddha, the refuges, five precepts, meditate for 15 mins and say a quick metta prayer. In the evening, I chant homage again, recollection of the three treasures, affirmation of refuge in three treasures, five subjects for daily recollection, 30 mins meditating, and finally the anumodana chant. After that I listen to a dhamma talk online, read suttas or texts provided by various scholars.
All this is according to Access to Insight's "Lay Buddhist Practice" guidelines, found here: http://www.accesstoinsight.org/lib/authors/khantipalo/wheel206.html
. I find it to be quite effective in fostering the kind of faith and discipline I need in my life.
