Agree with most everything and will check our that interview, that attitude is how I try and live, but the last sentence is obviously not true. Taking heroin is a habit, going to a gym is a habit, and obviously one is much easier to stop whether either willfully or not.

I'd say the ease which you can pick up habits or drop them is extremely variable across the specific habit and person. (as a different example, someone with less social awareness will find it harder to pick up the habit of being a hospitable host than someone it comes naturally to, but once learned its probably fairly easy to maintain)

One of my favorite quotes is, "first the man makes the habit, then the habit makes the man" , and it works both ways, good and bad. I really think this is something that should be taught much more explicitly in school to everyone, rather than leaving it only in places like sports and the military.

Taking heroin may be called “a habit” but it’s not a habit. It’s an addiction with physical and neurological elements.

[justonenote]

it absolutely is a habit, the fact that it affects you physiologically via pharma does not make it not a habit. a habit is something you do habitually, that is the exact definition of the word, and the reasons people do them vary wildly. I used heroin as an an extreme example.

Going for a 5k jog every morning is also a habit that affects your brain chemistry, through different mechanisms, and can also be addictive. It's obviously much healthier, but its still a habit, that is reinforced via brain chemistry rewards etc (addictive in some people). It's not as widely seen or known but there is a small cohort of people who exercise becomes a problematic habit and ends up being detrimental to their health.

I suggest you check the definition of the words. I specifically wasn't talking about addiction because that is just one axis of what can make up a habit. Drinking water is a habit that is not addictive but pretty hard to quit. If you take a wider view there are tons of habits that are either harmful or positive, but have no addictive component, and have no chemical component, and are either hard or easy to pickup / drop.

Merriam-Webster does of course have addiction as a habit, but it singles it out as being different than other definitions https://www.merriam-webster.com/dictionary/habit

perhaps this is one of those definitions that are in flux and we are moving from taking drugs as a habit, to first having a drug habit, and soon, no longer a habit but an addiction.

I would have to say that in light of the other definitions of habit it does seem reasonable to separate them.
