I found the advice helpful because an "addiction" is something that controls you, whereas a "habit" is just a pattern you can continue or break. Or to look at it upside down, "addiction" offers an excuse, "habit" doesn't.
Any kind of pattern-break I find is easier when done in bulk -- change the furniture around, paint the room, get up at a different time of day, take a different route. The new patterns reinforce each other.
Former smoker. Nicotine is one of the most addictive substances out there. More so than cocaine.
And unfortunately, some people have more addictive personalities than others.
I mean when you have lung disease and are still smoking, you are serving an addiction. Not a habit.
That all depends on how you choose to look at it, which is what my post is saying. You can define "addiction", "habit", "pattern" or anything else in whatever way suits you. I'm saying for the purpose of quitting that addiction/habit/pattern, it's more useful to term it in a way that offers a way out than to term it in a way that locks you in.
