Most of us don't live in temples. As Zen practitioners, our expectation might be that if we did, we could just practice Zen 24/7 with no hindrance, no distractions, just practice, practice, practice. It's a nice idea, but only an idea. So how do we "practice as if our hair was on fire?" We treat each moment as if it were the most important moment ever--just experiencing it fully, doing whatever we are doing 100%. Sending an email? Send it 100%. Cooking a meal? 100% cooking. From moment to moment, just experiencing reality as it is without expectation of it to be different, or better somewhere else is our practice. As ZM Seung Sahn was fond of saying, "Just do it!"
