It's amazing how often executives are stymied by their inability to influence others. The typical scenario involves a talented, change-oriented leader who gets a shot at a more visible role. In the process of getting stuff done, he steps on a few (very influential) toes. Over a couple of years, the executive racks up some impressive accomplishments but finds that his success is hindered by the organizational minefields his actions have sown over the years. As a result, the executive tires of the level of effort required to move things forward and decides that it's time to move on.

3. his success is hindered by the organizational minefields his actions have sown over the years

4. И наконец
it's time to move on
