Cardinal virtues are four important qualities that help us be good people. They are: courage, temperance, justice, and prudence. Courage helps us stay strong and do the right thing even when it isn't easy. Temperance is about being able to control our desires and not get too carried away with wanting things or doing things. Justice helps us treat other people fairly and to do what is right. Prudence is about being wise and thoughtful in our decisions and actions. Having these four qualities helps us live our best lives and be the best people we can be.
