15 minute challenge

Before, I mentioned that I was going to try out the challenge of spending 15 minutes with God, twice a day. So far the time that I have spent with God has been great. I have found myself calm, peaceful, & cognitive. The problem is designating the time. As I have said before, I have no problem finding the 15 minutes e.g. driving the car, taking a shower, etc. It the designating the time as "God time" that's the problem.
