You can make this about anything you want. For example, I already worked with my faith when I became under-employed. By the time I was ready to quit smoking, I had to deal my surroundings and interacting with people.
Now to really send home the message that the exercise is whatever you want. I turned over excerpts of this book to my writers group and they pointed out that the virtue is about faithfulness and not faith. I actually heard a thud inside my head — It’s about being loyal? “Screw that, the work I did was in faith! Faith that you guys show up to our club. Faith that my car starts! Faith that I get this done!” I dangled my submission by the stapled corner. Well, not exactly, I processed it a lot slower than that. Wow, did I have the blinders on. You will see that I was able to bring it full circle. I’m convinced that I had to work on faith before I could become faithful. So do what you need to do.
