To the OP. You don’t have to be religious to understand that the 4 cardinal virtues, prudence, justice, fortitude, and temperance, are very helpful in navigating the mine fields of life. You would serve yourself well reading them, understanding them, and applying them to your life. It’s like when you learn to drive, you have to study the driver’s manual, take a test.
Then you get behind a wheel and put it into practice. You have a seasoned driver beside you, helping you. The reason is that we share the road with a whole lot of other people, all going someplace important. Then there’s icey conditions, pouring rain, fog, poor visibility, all contributing to a very awful car crash if we aren’t careful. Even if we are, there’s no guarantee the other drivers aren’t driving too fast for the conditions or have been drinking.

The cardinal virtues are like that, as well as the other virtues. You as a man, should you get married, are called to apply them to your life, to your family, and teach them to your children if you are blessed with them. This is why we go to church (one reason of many) and why having a ‘seasoned driver’ is so helpful to learn how to navigate life without crashing, hurting yourself and everyone around you. You have a higher calling than the life you are living now! I guarantee you, if you take this on, it won’t be boring. It will be a challenge, and the reward is in this life and eternal. God bless you today and guide you.
