They are Prudence, Justice, Temperance, and Fortitude. Prudence helps me decide what is good in every circumstance of my life. When I take the time to think of the consequences of my actions, I am prudent. When I don't do some things because of the bad consequences, that is prudence. Prudence is necessary for a happy and successful life.
Prudence helps keep the stress out of life.
Justice is a consistent decision to do what is right towards God and my neighbor. I respect the rights and duties of others. Justice brings harmony. Without justice, there is no peace. There are no rights without duties attached.
