What explained what leaders could and could not do?

Leaders are often constrained by organizational structures, cultural norms, and the expectations of stakeholders, which define the boundaries of their authority and decision-making. Their effectiveness is also influenced by their ability to inspire and communicate vision, manage resources, and adapt to changing circumstances. Additionally, legal and ethical guidelines play a crucial role in determining acceptable actions, shaping the scope of what leaders can realistically achieve. Ultimately, a leader's skills and understanding of these factors determine their capacity to influence outcomes.
