You will finally change when the pain of staying the same becomes worse than the fear of changing.
Or - when the desire to live a better life becomes stronger than the allure of your addiction.
There are two paths to this outcome; it becomes so devastatingly bad that you are absolutely desperate OR - your positive focus on a desire for improvement grows that desire to the point that it takes over.
So.... You can wait for it to get worse....
Or resolve right NOW and every day to take steps to grow your desire for better.
Anyway, you can do it!!
