So... welcome to maturity.
For Individual part, I am planning to launch an app for addicts so that they could also get benefit from same principles. I believe in that cue, routine, reward cycle. But, For creating app I need to do my own research for individual cases.
I managed to add a bunch of habits such as doing math at khanacademy, writing 500 words a day, measuring data points on my body such as blood sugar, weight, steps, sleeping time, pulse rate, and blood pressure.
You could also say, I put on my underwear after drying off merely out of habit and the underwear cartels make their cottony underwear so smooth merely to provide a pleasant reward for my ass cheeks. But, in fact I put on my underwear for a variety of practical reasons and the smoothness is not really a reward.
The snack break example was more to the point. That's a voluntary thing that becomes routine, but could be skipped with no social repercussions.
I'm more than my habits, Aristotle aside. I'm an economist and a programmer and a father. The last causes disruptive change to habits more often than not.
There's a reason it's called Gene EXPRESSION.
