For those who quit smoking after many failed attempts, what finally worked for you?

I quit smoking on August 1st, and I’m still going strong. This isn’t the first time I’ve tried to quit I’ve even stayed smoke-free for more than a year before relapsing. But this time, I’ve decided to never give up. I believe quitting smoking is mostly psychological. After all, no one smokes when they’re in the hospital, at work, or on a plane. I’ve also started training and going jogging every other day, which is helping me stay focused and motivated. For those of you who have failed multiple times before successfully quitting, what made the difference for you in the end? How did you finally make it after several failed attempts?
