Long-distance runners have to be very strange people. You have to really want to do it. You don't have to win or beat someone, you just have to get through the thing. That's the sense of victory. The sense of self-worth.
Running is something you just do. You don’t need a goal. You don’t need a race. You don’t need the hype of a so-called fitness craze. All you need is a cheap pair of shoes and some time; the rest will follow.
People loose tension when they run. The feeling of self respect will almost always increase. You accept yourself a little more.
Buy all shoes, both street and running, slightly longer and wider than your bigger foot. Also, avoid pointed shoes. You'll save yourself needless foot pain.
Once you find a warmup routine that works, repeat it as habitually as possible.
