Why should I practice running slow? I already know how to run slow. I want to learn to run fast.

Try for a goal that's reasonable, then gradually raise it.

If you come to think of it, you never see deer, dogs and rabbits worrying about their menus and yet they run much faster than humans.

By a persistent effort of will it is possible to change the whole body. The athlete must always keep in mind this concept of change and progression. He must never accept his limitations as being permanent, because they are not.

I was not talented enough to run and smile at the same time

If one can stick to the training throughout the many long years, then will power is no longer a problem. It's raining? That doesn't matter. I am tired? That's besides the point. It's simply that I just have to.

A runner must run with dreams in his heart.
