This quote by Leonardo da Vinci underscores the idea that the level of control or mastery one can exert over their environment is directly proportional to the control or mastery they have over themselves. It implies that personal mastery – the ability to understand, control, and develop oneself – is the foundation for influencing the world around us.

The quote suggests two interlinked dimensions of mastery: self-mastery and environmental mastery. Self-mastery refers to one’s ability to control their thoughts, emotions, and actions. It involves self-awareness, self-regulation, and self-improvement. On the other hand, environmental mastery refers to one’s ability to shape, influence, or control their external circumstances.

Da Vinci’s words imply that the two are not just linked, but that self-mastery is a prerequisite for environmental mastery. Without self-mastery, any attempt to control the environment will be ineffective because the individual lacks the discipline, focus, and resilience required to effect meaningful change.

In today’s world, this quote can be applied in various contexts. For instance, in the realm of personal development, it underscores the importance of self-improvement. If one wants to improve their circumstances – whether that means advancing in their career, improving their relationships, or achieving other personal goals – they must first work on improving themselves.

In the context of societal or global issues, the quote suggests that meaningful change begins with the individual. For instance, if we want to combat climate change, we must first examine and change our own behaviors and habits that contribute to the problem.

Overall, this quote serves as a reminder that the power to change our world lies within us. The first step to making a difference in the world is making a difference in ourselves.
