Used to run like crazy, one day will get back into it. Even did a marathon back a bit.
Running is about the mental side and consistency. I can't run for shyt on a treadmill, even if there is a TV. Too boring. I need to be outside with scenery and headphones. I think most people don't just start running and enjoy it or have it feel easy. Once you mentally have yourself ready to run you have to be consistent and keep running on a continual basis. Your stamina, lungs, and muscles all get better the more you do it, so it seems easier physically and gets mentally easier. If you run a few times then don't come back for a week or two, it literally can feel like starting over.
If you can do it consistently and don't even worry about doing crazy distances, just a couple miles you will build up your tolerances and before you know it you will off and going. I used to hate the first mile or two because I needed to get fully in the groove and miles done after that were actually easier for me.
Also wouldn't recommend doing big runs because you want a good workout if you know your body hasn't built up to it. Running involves the movement of your whole body and technique is really important. When you get too tired your technique will suffer and thats when you start noticing you develop foot, shin, knee, hip, or back issues. I can trace almost all my physical pains due to running because I didn't warm up properly or I was running when my body didn't want to run anymore. You learn to push yourself when you know you can get more out of yourself like lifting weights, but when your body is physically giving up, time to cut the workout off as you will just hurt something.
