I suggest something very different. It is talking with God. You can see this custom to some degree in psalms. King David was in fact doing this. But also he was able to write down his prayers. And it is probable that most people that have some feeling towards God do this once in a while.

But what I am suggesting here is to make a goal of this. To in fact take the long way to work and back so that you can spend more time talking with God or at least trying to talk with him.

[This idea was to some degree written about Lawrence, a lay monk.
