People do not generally live in their actions, in the present moment. They live in the past or in the future. Though they seem to be doing something now, here, they live somewhere else in their thoughts, in their imaginary problems and worries, usually in the memories of the past or in desires and speculations about the future. Therefore they do not live in, nor do they enjoy, what they do at the moment. So they are unhappy and discontented with the present moment, with the work at hand, and naturally they cannot give themselves fully to what they appear to be doing.
