The career world is like an ecological system: People occupy particular fields within which they must compete for resources and survival. The more people there are crowded into a space, the harder it becomes to thrive there. Working in such a field will tend to wear you out as you struggle to get attention, to play the political games, to win scarce resources for yourself. You spend so much time at these games that you have little time left over for true mastery. You are seduced into such fields because you see others there making a living, treading the familiar path. You are not aware of how difficult such a life can be.
