You have to want to stop. I smoked 13 years, stopped several times, but the final real stopping was not that hard.
What also worked quite well for me as a crutch were nicotine free cigarettes. I decided I'd smoke as many of those as I wanted. Started with 20 at the first day and it slowly reduced by itself over time, till at one point o completly stopped without even realizing it.
