It is facile to imply that smoking, alcoholism, overeating, or other ingrained patters can be upended without real effort. Genuine change requires work and self-understanding of the cravings driving behaviours.
The problem is that your brain can’t tell the difference between bad and good habits, and so if you have a bad one, it’s always lurking there, waiting for the right cues and rewards.
Once you understand that habits can change, you have the freedom and the responsibility to remake them. Once you understand that habits can be rebuilt, the power of habit becomes easier to grasp and the only option left is to get to work.
