Need Help Correcting a Very Bad Habit

That has been a bad habit of mine for years, never do it around the kids or my wife but was common place anywhere else.
The past year I've been trying to rededicate my self to Gods word. Been reading the Bible daily a bout 4 verses in 4 books a night ( it's a plan to read cover to cover in 365 days). Its not easy, I'm 50 and have been in construction and around others that have "the" language... but I have tried to slow down my instant thoughts/ reactions and replace it with something I've read...It works , it's not fool proof... it's just the dedication piece...slow your thoughts and it will change...
