Scrubbing the floor is a great way to pray, meditate, and use up nervous energy. If you are fantasizing about drinking or using, scrub the floor. I was told to do this by a CEO of a big Corporation when I told him that life was getting overwhelming. He seemed like an intelligent guy and I was surprised when he told me to do what I then considered to be a stupid, mundane action. But when I tried it, I found that my anxiety melted away.
Today I will scrub the floor, paint the wall, do the dishes, start that exercise program, or something else that will allow me to mediate and exhaust anxious energy.
