Basically, I have an addictive personality. In my teens and early twenties smoking and drinking fueled that. As I made the transition to a healthier lifestyle, my obsession turned to running and exercising. I have always maintained what I feel is a good balance.
I am aware that I am heading down a dangerous road, so I am placing some limitations on my "run streak." I am not running an hour a day or anything now, and haven't been over the course of the last 119 days. I plan on continuing with the "rules" to run at least one mile a day. And I plan on at LEAST two of those days be JUST the one mile. Even as a slow runner, a mile takes just 10-11 minutes. If I start to feel any weirdo aches or pains, this will of course be reconsidered.
As for part two, I realize that I'm probably addicted to exercising and also plan on placing a limit on the amount of time I am putting into this. I need to write out a training plan (I really love structure) and follow it.
For ME, this lifestyle is helping to take my mind off my unhappiness. I don't know if that is a good thing or a bad thing, but it is making me feel better for now, so I'm going to roll with it.
