Machiavelli’s quote implies that the most effective leaders are those who don’t strictly adhere to their promises, but instead are capable of adapting and adjusting their plans as circumstances require. This doesn’t suggest that such leaders are dishonest or unreliable, but rather that they are practical and flexible, willing to change their strategies for the greater good.

In a political context, this could mean a leader making certain promises during their campaign, but once in power, they find that they need to modify their plans to suit the realities and challenges of governing. This concept is also relevant in military strategy, where a general might need to alter their promised tactics in response to changing conditions on the battlefield.

This idea can also be applied to personal development. It’s important to set goals and make commitments, but it’s equally important to be open to change. For example, someone might have laid out a particular career path, but if they discover a new passion or interest, they might need to break their initial promise and follow a path that brings them greater satisfaction.

Essentially, this quote promotes adaptability and pragmatism as key traits for successful leadership. It’s not about breaking promises for personal convenience, but about having the courage and wisdom to change direction when the circumstances call for it. This perspective challenges the traditional belief in the importance of always keeping one’s word.

However, it’s crucial to note that this doesn’t justify breaking promises lightly or irresponsibly. Integrity and trustworthiness are still essential traits for any leader. Any decision to break a promise should be made with careful consideration of the potential consequences and the greater good that might be served.
