Its pretty simple. The first thing you have to do, friend is to stop saying disgustingly demonic things. When a thought that has no other purpose then to promote trash comes into your mind and your wife is in earshot, dont say it. Maybe you can just make a

face and keep that thought to yourself like people who dont tell you what they're laughing at.

After this is a very hard concept called "doing the right thing" where instead of doing the wrong thing you instead, do the right thing. These concepts are very simplistic in nature but obviously the path of good is something we all see in front of us blatantly but choose to choose demonic roads because of their alluring nature. Sadly, friend, these paths lead to dead ends and thats so demonic.
