Mine is mostly informal - not ritual prayers for the most part, but my own speaking to the Divine, to the BVM, and to my deceased spouse.
If I remember, upon awakening, I thank God for being granted another day and ask for the strength and wisdom needed.
Grace before meals, again if I remember - average once per day.
Some praying while driving, and sign of the cross upon stopping for a red light.
Best praying at night, again informally, speaking to Each of the Trinity; thanking for the day just passed and acknowledging misdeeds and deeds not done.
Some special intentions throughout the day for those in need.

I no longer feel guilt, if I ever did, for that which I do not accomplish, as I believe the Lord knows my soul and my capabilities and struggles and loves me despite my imperfections. And, yes, I spend too much time on the internet.
