I've realized that there are two kinds of people in the world.
Those who prefer to talk in terms of efforts and those who like to talk about results.
So you will get the politician, or the manager, or some other worker, who talks endlessly aboutthe number of hours put in, the number of meetings attended, the number of presentations made and so on. But they will rarely talk about what they actually achieved.
Then there is the rarer breed that talks very little about the effort and focuses instead on the results. So you'll hear them talking about targets met, profits realized, development work completed, missions accomplished.
As a manager, your main job is to hire the second type of person. If you can find him, hire him and retain him, you don't have to worry much about managing him.
