American Zen teacher Joko Beck in Nothing Special:

There is a foundation for our lives, a place in which our life rests. That place is nothing but the present moment, as we see, hear, experience what is. If we do not return to that place, we live our lives out of our heads. We blame others; we complain; we feel sorry for ourselves. All of these symptoms show that we’re stuck in our thoughts. We’re out of touch with the open space that is always right here.
