Whoa this thing blew up. I had no idea it would be this popular
My advice for running as someone who never enjoyed it, ever, you just have to do it. I know that is the cliche answer, but its the truth. Once your body is used to it, you will have a much better time at it. Some things that definitely help, are getting the right shoes. Whether you decide to go barefoot or nice running shoes, you should find a good running store, and get fitted for shoes. They have you run and video you, to find out your foot strikes. This was the one thing that helped me out a lot. I did the barefoot thing for a long time, and really enjoyed it. But there is nothing like running in a proper pair of shoes. And like Sed8 said, best to start out slow, and slowly push yourself further. Another thing that helped me when i first started a few years ago, run outside. Treadmills are nice, but they can act like a crutch. If you map out a nice 3-5 mile loop, and get tired 2 miles in, you have to make a 2 mile trip back. You can run, run/walk, or walk. All of which are better alternatives than just stopping. I will add, that I am not an expert when it comes to running. These are just things that I found helpful for me. Anyone feel free to chime in, or correct me, if anything I said was wrong.
