I intend to try some fasting this year, based on the traditional Catholic calendar (I can provide a link if you like), and use part of that time to do some internal examination of conscience. Not so much from a penitential point of view, but more of a "How can I grow myself while I shrink myself", if that makes sense. By eating only the food I need to right now, the less I have to buy. My flour and oil jars will always be full, so that I will never be hungry (I forget which gospel that is in, I think it's Mark). By taking only the food I know I will eat when we go to the food bank each week, there is more to share with others who can't afford to buy healthy foods, like produce. By sharing, we help others. By not being selfish, we help ourselves.

I'll have more to add, but my brain is drawing a blank right now, LOL. :-)

fisheaters.com/beingcatholic.html It's my go-to site for learning about how my grandparents lived a Catholic life. Also, traditio.com/cal.htm has the traditional liturgical calendar for the entire year.

Glad to help. There's so much there to discover, I'm still finding new stuff even after 8 years of using it.
