One good piece of advice I have received regarding lenten penances (“giving something up”) is to construct your penance around your most troublesome fault. For instance, I have a problem with gluttony. Put a box of gluten-free (a sad necessity for me) cookies in front of me, and I won’t realize how much I have eaten until the box is gone. To try to help control that, I have given up cookies, cakes and candies for Lent.
A person I know wants to get a better handle on his anger. He feels he is sometimes unjust because of his strong emotional reactions. His idea was to keep a journal and note each person he gets angry with. He then writes down either something to admire and appreciate about that person, something he can do for them, or a prayer for them.
I thought that was a nice and creative approach for Lent that very neatly encompasses the true purpose of the liturgical season. If you have some equally creative practices, I would love to hear about them.
