In response to growlerius:
Yes.. I did have a specific breakthrough moment. It went down pretty much exactly how my original post describes. For my whole life.. the extent of my running was nothing more than my "30 minutes of cardio" to supplement my workouts in the gym. It was something I was supposed to do.. felt I had to do.. but never WANTED to do. It was.. "get on the treadmill, turn on sportscenter and get it over with" all to reduce my bodyfat.. so I could look better.
So after a rough couple years of gaining weight and unhealthly habits (including excessive drinking), I decided something had to change. I didn't go out with any specific intentions other than a change of lifestyle. I really didn't even plan on attempting to be a runner. I hadn't signed up for a 5k.. or any race for that matter. I didn't subscribe to a training plan.
I originally began converting my daily walk with with my dog into a jog/walk. I could barely get through 2 miles. A couple days later I tried 3 miles. 3 weeks into this and I was able to run 3-4 miles, but wasn't enjoying it since I was still thinking of it as something I HAD to do to get healthy again.
Then one day, without any plan, I was about 4 miles into my run and I thought to myself.. "why am I always thinking so negative about these runs, I mean it really doesn't hurt.. what is it really that I dislike about it.... ummmm... NOTHING?" "why am I only running 4 miles today?.. what is making me stop at 4 miles?"
So I just said "fxxx this" and kept running.. just to run. My breathing became quiet.. my stride became smooth. I ran 7 miles that day. Because that is how far I WANTED TO RUN!
Always sore after the first time running a new distance. I would always take a day off between runs to avoid any overtraining issues/injuries since I was so new to this. Eventually, 7 miles turned into 10, which turned into 15. I literally never even considered stopping during a run. It never entered my mind. I WOULDN'T ALLOW IT! I did tweek a hammy during a hilly half marathon.. so I took a couple days off.. and good to go. I will never run through an injury. That's just silly... and NOT the point of this message. GEEEEEZ 
I now rarely take a day off. I run 80-100 miles per week. I can't wait to get up at 4 am to go run. I rarely use an ipod. I run with a
on my face.
I have now committed to running at least 52 events this year. I run a minimum of 1 race per week and often 2. All disciplines.. 5k's to ultra's. It doesn't matter. I just love the adrenaline I get before every race. Most days I won't even be satisfied with the miles of the race. On the shorter 5-10k's I will generally run again later in the day. In fact.. the last charity cycling ride we did a few weeks back I new that the 60 miles on the bike wouldn't be enough, so I ran 7.1 miles to the start.. and after the ride.. ran back home (in the pouring rain). (my gf drove my bike and gear) I love competing against my personal records which I break EVERY WEEK. I'll be running my first ultra marathon in 3 weeks and can't wait. I actually dream of running.. literally!
And to think.. all those years I had the wrong impression about running. I thought it was something I had to do.. and it turns out it's all I WANT TO DO! 
***as a follow up to this. My longtime girlfriend (6.5years) and future wife has preached ever since I met her that she hates running.. "I'm not a runner" she would say. Well.. long story short.. she ran 16.5 miles with me yesterday morning and races most of the events I race and is often placing in her age group.
