Being content is a great skill for quitting. “Father, help me to be content.” There are days when I pray this constantly.
Turning from sin is a great skill for quitting. I pray constantly, daily, often hourly, to turn from sin and to turn from lust. Remember, any habit that involves sin (that you are quitting) will be prompted by other sins. Consider making it a habit to fight bad thoughts, and wrong TV/computer/phone garbage.
Second, stop hanging around with people who increase your temptation. Find healthy people to be around. Get involved with church groups, sports groups, and 12 step programs. Determine to be the person who makes that program fun, interesting, and informative. If you learn anything here, bring a couple of notes and help others there. Doing that is part of purpose.
Third, be obsessed with adding your #1 rated skill today, and this week/month.
Fourth, consider taking notes on future skills you want to add, but add skills in a specific order. My #1 is the habit of often quoting a quitting verse first. Work on your #1 needed skill first.
Fifth, know “All of your triggers.” Have all of them written in a section of your notebook. Consider writing first in your notebook, “When triggered I will vigorously quote my quitting verse. I will pray fervently. I will “immediately” start to work on quitting, and will go to a quitting site as soon as it is humanly possible.
Finally, people who quit are not necessarily more disciplined than you. But they do know “What to do when triggered.” Learn as much about what to do as possible. Study it online, take notes, pray about it. It is a top 5 skill for quitting.
