Those concepts are in the '7 habits of highly successful people' - but introduced as the circle of influence and the circle of concern. The idea promoted is that stress will result when you try and deal with things outside of your circle of influence, and you have to keep operating within that circle.
Obviously, very few pop-self-help books like 7 habits contain genuinely new ideas, and the concept is borrowed from much older ideas. Nonetheless I think it was helpful to me when I first read it. It has a message of both keeping perspective and also reducing useless stress, but at the same time telling you that the only way to take action is to increase the amount of influence you have.
