It is not uncommon for good habits to morph into bad habits. This often happens when good habits are taken to an extreme. This is why people should be aware of their behavior, even when it might seem positive.
People who want things to be the very best can seem to be very upbeat people. At least that is true until they go too far. When their leadership becomes nit-picking perfectionism, their good habits have turned into bad habits. Once it has reached such a point, it is hard to salvage the situation.
