Sandi, that is very interesting! I have heard of people "taking on" a discipline instead of (or in addition to) giving something up. Like an extra spiritually based class, read a new book, etc.
Last year I gave up watching QVC for Lent, and my bank account sure felt better about it!
Seriously, though, it can be addicting because they have such beautiful jewelry, accessories, clothes. . .etc, etc, etc!
Haven't decided what to give up this year yet. Maybe something food oriented. Or maybe it should be my extra spending ~ that's a toughie.
