Or - a different way of thinking about it, may you bring many blessings to it. Instead of giving up something, why not choose to be extra generous in some way each day. Do something you don't have to do for someone. Do something without getting asked. Do something without getting noticed.
Make the world better in some small, unnecessary way, each day. And then at Holy Week, look back and see what has happened to it and to you as a result.
That's what I'm going to try this year, anyway.
