"You can have no dominion greater or less than that over yourself"

This quote by Leonardo da Vinci talks to the significance of self-discipline and self-mastery. It recommends that the greatest power we have is the power we have over ourselves. We can pick how we believe, how we act, and how we respond to the world around us. We can select to be kind, generous, and caring, or we can pick to be selfish, unkind, and ungenerous. We can choose to be disciplined and focused, or we can pick to be lazy and unfocused. Ultimately, the power to make these choices lies within us. We have the power to form our own fate and to develop the life we desire for ourselves. By working out self-discipline and self-mastery, we can become the best version of ourselves and live a life of function and fulfillment.
