Just reading about the positive approach to challenge in psychology. People expect and even appreciate an opportunity to show themselves capable. It might have to do with our pleasure in participation making us feel like we belong. Who would we be if there were no expectations on us? As a small business owner I had to set standards and clear expectations and sometimes it felt harsh but almost always would take the time to talk it through. Some people I had to fire because they poisoned the work atmosphere by challenging everything. Our work was potentially dangerous and we relied on each other. And, someone needs to make decisions or things just stop happening.
