Cleaners have a dark side, and a zone you can’t enter. They get what they want, but they pay for it in solitude. Excellence is lonely. They never stop working, physically or mentally, because it gives them too much time to think about what they’ve had to endure and sacrifice to get to the top. Most people are afraid to climb that high, because if they fail, the fall will kill them. Cleaners are willing to die trying. They don’t worry about hitting the ceiling or the floor. There is no ceiling. There’s no floor either.
