SOS believes that you need to decide more firmly than the last times you decided not to drink and then stick with that and thereby stay sober for life.
SMART believes you need to see more clearly that drinking or procrastination, or whatever you want to change has more negatives than positives to it for you, and by understanding that and identifying your ongoing thoughts about drinking as false, you will thereby stay sober for life.
Rational Recovery believes you have an inner Beast that makes you drink, and that you need to identify and name your Beast. After you've done that, whenever your Beast starts barking at you to take a drink, you simply tell the Beast you are going to ignore it's barking. As long as you do that you are guaranteed to not drink for life.
Science is a wonderful thing.
