You think that your attention is in the present moment when it's actually taken up completely by time. You cannot be both unhappy and fully present in the Now. What you refer to as your "life" should more accurately be called your "life situation." It is psychological time: past and future. Certain things in the past didn't go the way you wanted them to go. You are still resisting what happened in the past, and now you are resisting what is. Hope is what keeps you going, but hope keeps you focused on the future, and this continued focus perpetuates your denial of the Now and therefore your unhappiness. p. 43

On the surface it seems that the present moment is only one of many, many moments. Each day of your life appears to consist of thousands of moments where different things happen. Yet if you look more deeply, is there not only one moment, ever? Is life ever not this moment? This one moment, now, is the only thing you can never escape from. The one constant factor in your life. No matter what happens. No matter how much your life changes. One thing is certain. Its always now. Since there is no escape from the now, why not welcome it, become friendly with it.

Whereas before you dwelt in time and paid brief visits to the Now, have your dwelling place in the Now and pay brief visits to past and future.
