This is a very profound and practical idea. We often try to change ourselves through thoughts or desires, but real transformation begins with actions. When we systematically repeat useful habits, from healthy eating to regular exercise or meditation, they gradually shape our identity. That is, there is no need to wait until we “become” healthy or disciplined; it is enough to simply act, and our personality will change along with our actions. This rule seems simple, but its constant application is a true art of self-improvement.
