Do you devote yourself to something -- habitually, obsessively, ardently, enthusiastically -- surrender yourself to a cause, object, or pursuit?
Runners and daily exercisers get endorphins -- opioids (a compound produced by your glands during exercise, excitement, pain, consumption of spicy food, and orgasm) that resemble the opiates in their abilities to produce analgesia and a feeling of well-being.
I am not a junkie, but I've been a daily dancer person all my life. I don't dance to get a HIGH from doing it. I just do it.
You can overdo running, dancing, or any of the things you do that create the HIGH or high-point of your day. You could be a sex addict, a gamesters on your computer, gung-ho about gaining/winning /losing in Farmville, or Mafia Wars , and get the LIFE IS GOOD, LIFE IS OKAY sense of calm and hope.
Hey, you could be an eating addict and get that glow from eating six or eight or ten times a day. Or a "reading addict, a writing addict, a texting, a phone chatterer addict.
(Actually, I think facebooking -- contacting, communicating with friends, new and old, who are lonely, bored, needy, responsive, and often pretending to be their younger selves), is very addictive..
Okay, anything you do -- do often, do routinely -- can give you endorphins. Does it matter? Is it creating a need, a dangerous obsession?
