So, I'm starting to think of what I'm giving up. A couple years ago, I gave up caffeine and never turned back. Ended up being a great choice for me.
Last year I gave up surfing the net during work. This made me ultra productive at work. I'm going to try it again this year and see if I can carry it out after Lent.
The only other thing I am considering is going back to the Catholic church. I've been meaning to do it, but I haven't setup a meeting with a priest to see what I have to do about my marriage and kids. My marriage was never overseen by a Catholic priest and my kids aren't baptised in the Catholic faith. If that ends up being a whole ton of issues, this quest will end up short. Otherwise, I'll be attending two churches each weekend: The Christian service I currently go to (wife's faith), and the Catholic mass.
