Everyday accomplish some wins. Have spiritual wins: meditation, self-reflection, prayer (if it's appropriate for you). Accomplish mental wins: Reading, writing, studying and learning new topics. And have physical wins: Running, walking, going to the gym, fighting lessons. Nothing can destroy iron except its own rust, in the same way no one can destroy you, except your own lack of discipline and striving to become that best version of yourself. Onwards Gentlemen.
