I am such a creature of habit, not as much as my college roommate, but I tend to do things the same way each time. Here is an example of my attempt to "change it up a bit".
I decided I would enter my usual grocery store from the other door and run the store in the opposite direction. I spent twice as much time in the store, because I kept having to go back up and down the aisle looking for things I had forgotten on my list. It was just plain pathetic!!!
My attempt to mix things up, needs to start with smaller things in my life. Like brushing my teeth, before putting on deodorant, or something like that. My the direction of the grocery is out of the question.
