rockin, SO COOL!
I am not sure I believe that we have to replace one habit with another, although in the short term it might look like it. Consider that at one time we were all children and did not smoke, drink, etc. But people who are stopping drinking often increase their smoking, if they smoke... and people who are stopping smoking sometimes up their eating. I suppose the trick is NOT to replace one habit with another but to get off the merry-go-round.
I also think it matters what we call it. An addiction is out of control. We use the word loosely, but a true addiction is overpowering. People will do virtually anything to obtain the addictive substance. No one here has sold their child for a Hostess Twinkie, right? (I hope not!!!)
Obsession isn't the same as dedication or determination, in my view. Obsession is a 24/7 mental process. Dedication or determination means you do what you have to do, but you also do other things as well. No athlete trains ALL the time. A lot of the time, yes, like a job--but not ALL the time.
Commitment... that's where it's at. The sum of dedication and determination. That's the thing that gets us through the days when we're not motivated, when we don't feel a lot of enthusiasm, when some food is calling our name.
Ahh... I think I need another cup of coffee...
