Also unlike many people I know, I don't listen to anything while running. Running is a time for me to think about stuff that I'm too busy to think about during the day (e.g. contemplating life issues or is 1*0=0 because of 1 or 0)
I used to think anything slower than 10:00/mile is jogging and doesn't qualify as running. This harmed motivation since when I was just starting I couldn't actually get faster than that every single run.
My first jog was like 500 meters, and I was exhausted, but I've did like 20 more sessions since then, and I see a steady increase of distance I can go before I reach my first point of exhaustion.
Now I can go 1000 meters, and recover faster, and I even feel slightly generally better during my everyday life.
Since I'm not pushing myself too hard, it is actually kind of enjoyable and even though I do not have a regular routine, never before I had the spontaneous urge to jump up from my chair at the end of the workday and go running with a smile on my face.
Over time the speed and duration you can run will get better but your heart rate will stay the same.
I would recommend trail running as it is much more dynamic and you are less likely to get overuse injuries like people who run on concrete for many miles get stress fractures. Bonus points you get out in nature.
Our expectations change. We learn to expect a faster heart rate.
"People who are just starting out" may experience "blow up their heart rate" as unpleasant; and then they learn to expect a faster heart rate when they run.
These days my running heart rate peaks at 3.5x my at-rest heart rate.
On week four "I am really doing this". And on week 12 "impossible to stop now".
Aim for those and you will be unstoppable.
Those aren't the days that matter.
The days that matter are rainy. They'll be bastard hot and humid. Cold and windy. You'll be annoyed because you don't have time. Something will hurt and there'll be a thought in the back of your head that maybe if you skip today (and the next run too?) then you'll feel better.
Those crap days are the days that count. Those days are money in the bank. Enough of them and you get great days. Every day like that is a day where you can think that running for you is like a smoke to a pack a day man. It's not something you do it's something you are.
