Tim brings up excellent points. We wag our fingers at addicts, but aren't most of our activities for pleasure, stress relief, to get rid of boredom, to achieve some affect?
I drink hot chocolate daily because I crave the sweet. BTW, that's exactly why I don't drink. I'm from a family of alcoholics, and that gene for alcoholism is one that regulates sugar. So that's my addiction, sugar. It's just more socially acceptable in our society as long as I'm not obese. If I get obese then fingers will wag at my sugar consumption.
But all actions have a physical response, and underlying that is generally some sort of craving. There are a lot of things I do now, that I enjoy, that don't have underlying craving any more, and that I can let go. But I'm well aware that I'm crave mental stimulation via reading and educational videos, I crave certain foods, I crave certain entertainments.
We are all creature of habit craving. That is an important part of becoming mindful. Seeing where the craving is hiding, studying it, and letting it go, no matter whether it's wine, soda, walking in the woods, escaping through music, art, TV, or what have you.
