I teach stress management classes for government agencies and corporations around the world. What I teach is basically the Sanskrit term nishkam karma, which means “to act without desire for the fruit of the action.” Just strive to do the right thing each moment and the result will be the result.
Suppose you are skiing downhill, and trying to make a good time to the finish of the run. You of course have a goal, but if your attention is down the hill at the goal, you will miss what needs to be happening here and now right under your skis.
