Success is always a work progress
Its been almost 3 years since I stopped drinking, but I try not to think of it as a success. Its always something I will live with and always something I am working on. I still have an occasional urge and I've used the techniques of SR to help me. I have other areas of my life that I also need to work on and I am apply the same principles to these things (food/ overeating is a huge one).
What I like most about SMART is that it isn't an all other nothing mindset. Yes, I've been sober for a long time and I know I can never drink again (moderation in the past has been a miserable failure) but I also know that the longer I am successful the more tools I gain in correcting any mistakes I may make in the future. That is not giving me leeway to drink again, but if I ever did, I will not be back at square one.
