I don't believe in giving things up; I'm more interested in taking things on, and I don't need encouragement to punish myself. I have friends who have gone vegetarian for Lent, and I was one, year-round, for more than 15 years. I respect that choice, very much, but I'm not following it. The reasons I'm not, now, have partly to do with the vegetarian options at school (sometimes great, often not), and partly because I spend a lot of time with omnivorous friends. I don't want to ask them to change for me.
It's very, very easy to beat myself up; my practice in this season needs to be gentle. I've pretty much decided to revive my on-again, off-again prayer journal. I may do the Ignatian examen in that context.
What are you doing for Lent?
