No Bad Words...

As I have been studying proverbs I have seen that it mentions to not mention bad or corrupt words. I have been taught to never say "bad words" because it sounds horrible and because God doesn't like it. I can't say that I NEVER say bad words, it is really hard for those words not to stick when you have a bunch of people at school saying them around you. I have even heard that some of them have "swear tuesdays" which to me is kind of pointless because that does not benefit them in any ways. One of the places in proverbs in which it is pointed out is in proverbs chapter four  verse 24. The verse before it even says to guard your heart for everything that we do flows from it. I want to guard my heart and to keep my mouth from perversity. I want to please God and I only want things that are contributing to my life positively to come out of my mouth. I want to work in clearing my vocabulary from "bad words" completely.
